Abstract
The low-cost and more efficient adsorbents of Azadirachta Indica (Neem) are charcoal, bark; leave and root were investigated for its optimistic de-colorization of wastewater containing a dye. The effect of various parameters such as contact time, pH, temperature and adsorbent dosage has been carried out in this study. Two isotherm models were developed for compliance with Langmuir and Freundlich isotherm. The results of the goodness fit test based on Root Mean Square Error (RMSE), R2 for Langmuir and Freundlich models were given as, for pH (0.9745 – 0.99919), (0.4831 – 0.9999) for Adsorbent Dose is (0.9034 – 0.9221), (0.4689 – 0.9884) for contact time (0.9494 – 0.9513), (0.4677 – 0.9990) and temperature (0.9264 – 0.9349), (0.3755 – 0.5849) respectively. Both models were found to be best fit on decolorization of dye with contact time, pH, temperature and adsorbent dosage. pH 5 value indicated that adsorbent was effective in the removal of dye.
