Experimental Study for Efficiency of Natural and Modified Seagrass as Low Cost Adsorbent for Removal Malachite Green Dye

The removal of dyes from wastewater is a matter of great interest in the field of waste water treatment. The effluents from many industries often contain one or more toxic dyes. Therefore, an increased interest has been focused on removing such dyes from wastewaters. Malachite green MG is one of the most common water soluble dyes. In general, several methods are used for the removal of dyes from wastewater. Among the treatment methods, adsorption is comparatively superior. Sea wastes are renewable and available abundantly at no or low costs. In the present study, the use of low cost, abundantly available, highly efficient and eco friendly adsorbent biodegrade seagrass materials, as a sea by product has been reported as an alternative to uptake of malachite green MG dye from its aqueous solution. Batch experiments were used to carried out for the removal of Malachite Green dye from its aqueous solution using seagrass material as adsorbent. A batch mode was used to study several factors, dye concentration solution 10 90 ppm, adsorbent dosage 15 35 mg, contact time 0 120 min, size 355 710 , pH 3 11 and agitation speed 150 250 . The results indicated that the removal efficiency increases with the increase of adsorbent dosage, contact time and pH, while inversely proportional to the increase in size, dye concentration solution and agitation speed. The adsorptions resulting data were in agreement with both Langmuir and Freundlich isotherm models according to the regression analysis, and the kinetics data followed pseudo second order kinetic.
