Adsorption of Chromium (VI) Using Neem Leaves and Pomegranate Peels

Download Paper


Heavy metals, when present beyond prescribed limits can be very toxic to the water in which it is dissolved. Adsorption has been used as a suitable and economical water treatment process to remove heavy metals. Many studies have been conducted to successfully remove the heavy metal by using different materials. Different materials have different chemical constituents; hence, a material that is very effective in removing one heavy metal may prove to have a poor efficiency in adsorbing, or removing, another metal. For this research, neem leaves and pomegranate peels were used as the adsorbent to remove Chromium from wastewater to compare the results of both the adsorbents. The synthetic wastewater was produced in the laboratory to conduct the experiments. Batch tests were conducted to obtain the optimal materials and conditions combinations. Different conditions are to be tested for pH 5 and adsorbent dosage. Maximum Removal with neem leaves was 65.254% and maximum Removal efficiency with pomegranate peels were 95.284%. Results have to be analyzed using Freundlich and Langmuir equations to fit the experimental data so that kinetics of the process can be obtained.
