Removal of acid blue 25 dye by using dried water hyacinth from aqueos solution
Water hyacinth(Eichhornia crassipes)is a free floating aquatic weeds that robustness in its growth used as an adsorbent to remove Acid Blue 25 dye from aqueous solution. The parameters studied include the adsorbent dosage,initial dye concentration,pH,and also contact time in a batch adsorption proce...
