| Abstract: | This study deals with the use of low cost,
easily available, high efficiency and ecofriendly adsorbent as an ideal
alternative to the currently used expensive methods of removing dye from waste
water. The potential of mango bark powder for the removal of malachite green (triphenylmethane
dye) from simulated water has been investigated. Studies are conducted to
delineate the effect of pH,
temperature, initial dye concentration and adsorbent concentration. Equilibrium
isotherms are determined to assess the maximum adsorption capacity of the
adsorbent. The adsorption data have been correlated with Freundlich and
Langmuir isotherms which are used to suggest a plausible mechanism of the
ongoing adsorption processes. The maximum adsorption capacity obtained from
Langmuir equation is found to be 4.22 × 103 mol.g-1 on
mango bark powder. The adsorption of dye is found to be a second–order rate
equation. Thus, low cost mango bark powder can be an attractive option for dye
removal from diluted industrial effluents. |
