An Experimental and theoretical study has been conducted on the adsorption of methylene blue dye using activated carbon prepared from babul seed by chemical activation with orthophosphoric acid. BET surface area of the activated carbon was determined as 1060 m2/g. Adsorption kinetics. equilibrium and thermodynamics were investigated as a function of initial dye concentration. https://fitnessgravesyardes.shop/product-category/interval/
