Despite all that has been published on the American Civil War, one aspect that has never received the in-depth attention it deserves is the widespread use of landmines across the Confederacy. These “infernal devices” dealt death and injury in nearly every Confederate state and influenced the course of the war. Kenneth R. Rutherford rectifies this oversight with America’s Buried History: Landmines in the Civil War, the first book devoted to a comprehensive analysis and history of the fascinating and important topic. Modern landmines were used for the first time in history on a widespread basis during the Civil War when the Confederacy, in desperate need of an innovative technology to overcome significant deficits in materiel and manpower, employed them. The first American to die from a victim-activated landmine was on the Virginia Peninsula in early 1862 during the siege of Yorktown. Their use set off explosive debates inside the Confederate government and within the ranks of the army over the ethics of using “weapons that wait.” As Confederate fortunes dimmed, leveraging low-cost weapons like landmines became acceptable and even desirable. The controversial weapon was the brainchild of Confederate General Gabriel J. Rains (who had experimented with explosive booby traps in Florida two decades earlier during the Seminole Wars, and other Confederates soldiers developed a sundry of landmine varieties, including command-controlled and victim-activated. The devices saw extensive use in Virginia, at Port Hudson in Louisiana, in Georgia, the Trans-Mississippi Theater, during the closing weeks of the war in the Carolinas, and in harbors and rivers in multiple states. Debates over the ethics of using mine warfare did not end in 1865, and are still being waged to this day. Dr. Rutherford, who is known worldwide for his work in the landmine discipline, and who himself lost his legs to a mine in Africa, relies on a host of primary and secondary 1. Language: English.

The entire project is divided into six chapters. The content of the project presented in each chapter is given below. CHAPTER-I INTRODUCTION. Chapter I deals with the introduction and background history of various types of environmental pollution, particularly due to discharge of dyeing industry effluent. Review of literature on the removal of dyes using various adsorbents was also presented. CHAPTER-II SCOPE AND OBJECTIVES. Chapter II deals with literature survey of various low cost adsorbents uses for removal of dyes, scope and objectives of the present work. CHAPTER-III MATERIALS AND METHODS. This chapter deals with experimental procedure for the preparation of activated carbon from parthenium hysterophorous (L) and removal of two different dyes from the aqueous solution by adsorption methods. CHAPTER-IV RESULTS AND DISCUSSION PART-I ADSORBENT CHARACTERISTICS. This chapter discussed the results of the comparative physico chemical surface characteristics of the prepared of activated carbon. The XRD analysis depicts the presence of nano particles. The FTIR analysis depicts the presence of various functional groups.
The sugar industry waste water is reach with organic contamination like COD and BOD. Adsorption is an effective and low cost universal technique for the removal of organics. Effect of Mango shell and Coconut shell char is heart of this book with respect to particle size and activation. Activated Carbon is more effective than Non-activated charcoal and Powder size charcoal/ carbon is more effective than Granular size. Coconut Shell Powder Activated Carbon is most powerful, Whereas Mango Shell Granular Charcoal is the weakest adsorbent among all 8 adsorbents.The decrease in particle size and Activation process increase the removal of organic contamination. All 8 adsorbent follow Fruendlich and Langmuir Adsorption Isotherm. Adsorption intensity (n), Adsorption energy (b), Adsorption capacity (K, th0) and correlation co-efficient parameters are well fitted to graphical representation.
This book deals with the removal of organic impurities (dyes) from water phase. The adsorption performance of various low-cost waste materials, such as rice husk, sawdust and fish scale is reported. The adsorbents are mainly disposed off as wastes and can be efficiently utilized for adsorption of various organic dyes present in water. The impact of various operating parameters, such as adsorbent dose, contact time and temperature on adsorption was monitored, and consequently the optimal experimental conditions were established. Experimental adsorption data were modeled with various isotherm models. The model which provides a very high degree of correlation with experimental adsorption data can be used in design applications. This book also reports that activated saw dust can be used with greater effectiveness for the removal of organic matter from water phase. This would be of worth not only to the manufacturing industry in terms of reducing cost of dye contaminated water treatment, but also to minimize the impact on the environment. The present study clearly indicated that bio-waste inspired materials are efficient as low-cost adsorbents for the treatment of dye laden wastewater.
Master's Thesis from the year 2018 in the subject Engineering - Chemical Engineering, grade: 3.96/4.00, Addis Ababa University (Addis Ababa Insititue of Techology), course: Environmental Engineering, language: English, abstract: The general objective of the thesis was investigation of acid treated lemna minor as an adsorbent for removal of Cu (II) and Pb (II) from aqueous solution. Are there sustainable and available bio adsorbents such as lemna minor (duckweed) that can be used for the removal of heavy metals? Can the emerging bio adsorbents actually replace activated carbon which is very expensive adsorbent common today? What is the optimum Operating parameters for biosorption of metal ions under batch studiesHeavy metals are chemical elements with a specific gravity that is at least 5 times the specific gravity of water and are toxic or poisonous even at low concentrations. With increasing generation of heavy metals from industrial activities, many aquatic environments face metal concentrations that exceed water quality criteria designed to protect the environment. They are highly dispersed in a wide variety of economically important minerals. They are released to the environment during mineral extraction process. Therefore, mining activities are the first anthropogenic source of heavy metals. These heavy metals have potential health risks associated with metal uptake via food chain, dermal absorption or inhaling. High levels of exposure to heavy metals have been proved to cause cancer, organ damage, joint diseases, and in extreme cases, death. Several processes exist for removing dissolved heavy metals, including, ion exchange, precipitation, ultrafiltration, reverse osmosis, electro dialysis and activated carbon. Many of these approaches demand high energy, high cost, advanced operational requirements, result in large amounts of sludge requiring treatment or difficult to treat and be disposed of in an environmentally sound manner, or do not enable recovery of metals or material.
This book deals with water pollution due to presence of hexavalent chromium from different industrial effluents and its adverse effect on flora and fauna of ecosystem. This paper also provide a low cost treatment method based on biosorption using activated carbon derived from rice husk, an agricultural residue and compares the performance with other biosorbent as well as commercial adsorbents. Various equilibrium and kinetic studies were reported here to quantify the performance of adsorbents.
