Adsorption of Hazardous Malachite Green on Low-Cost Adsorbents ab 79 EURO Inside the Mechanism Equilibrium Kinetics and Thermodynamics
Malachite green is a basic dye for wool, silk and for mordanted cotton. It is also widely used to dye materials such as jute, leather, ceramics and paper, in addition to being used as a cytochemical staining agent and has, in fact, been widely used as the most efficacious antifungal agent in the fish farming industry Its worldwide use in aquaculture will probably continue due to its relatively low cost, ready availability, and efficacy, therefore, potential human exposure to malachite green could result from the consumption of treated fish and from working in the dye and aquaculture industries. In spite of these applications not much kinetic data have been reported in literature. Relevant data on the kinetics of its reaction, especially with oxidizing agents would give an insight into the conditions best suitable for its reactions and the mechanisms of these reactions. Data generated in kinetic studies, especially in collaboration with data from toxicological studies and experts in fish diseases could be of importance in improving its uses, as well as its handling when used as an antimicrobial agent, as biological stain and in the dyeing industry
Malachite Green is the most widely used dye for coloring purposes and an extensively used biocide in the aquaculture industry. As such, a considerable amount of the used dye enters the natural environment through wastes. From an environmental standpoint, there is concern about the discharge of malachite green into aquatic ecosystems due to its reported mutagenic, teratogenic and carcinogenic effects. Amongst the numerous techniques of dye removal, adsorption is the procedure of choice owing to its low initial cost, high efficiency and ease of operation. A number of non-conventional low-cost adsorbents including natural materials, biosorbents, and waste materials from agriculture and industry have been proposed by several researchers for removal of malachite green from aqueous solutions. Adsorption of Hazardous Malachite Green on Low-Cost Adsorbents provides a summary of recent information about the use of low- cost materials as adsorbents for removal of malachite green. Attempts have been made to offer an insight into the adsorption mechanism, equilibrium, kinetics and thermodynamics of malachite green onto various low-cost adsorbents.
