چکیده
|
Methylene blue (mb) adsoption study using rice husk ash (rha) and peanut shell ash (psa) were investigated the effect of different parameters such as initial ph, contact time, adsorbent dose, dye concentration were studied. the adsorption % efficiencies of methylene blue on rha and psa were 84.5 % and 83.5 % respectively (in 120 minutes on 0.2 g adsorbent). the results further revealed that adsorption of mb on psa and rha occur by both physisorption and chemisorptions processes. the comparative studies revealed that both the adsorbents have similar removal efficiencies in 120 minutes. however, rha has faster rate of adsorption as compared with psa. therefore, it is concluded that both the rha and psa are good adsorbents for the removal of mb in water.
