Removal of Cr6+ from Synthetic Polluted Water using Fe Modified Sugarcane Bagasse & Peanut shell Powder

Unprocessed waste is dumped in lakes and rivers which possess a severe environmental risk through heavy metal’s contamination within the food chain, especially chromium Cr 6+ . It applies for sustainable development goals by using green solid waste as a precursor. This research mainly focuses upon the analysis of time effect for Cr 6+ removal by FeCl 3 modified biochar using sugarcane bagasse and peanut shell powder as biomass. Adsorbent preparation was done using Bench-Scale Fixed Bed Reactor (B-SFBR) and Cr 6+ was found using the calorimetric method. Characterization was done by BET, SEM-EDX, and FTIR. The highest Cr 6+ percentage removal was achieved by Modified Peanut shell Powder with 99.97% removal upon pH 2, shaking time 180 mints, speed = 150 rpm, dosage 0.3 g, Cr 6+ conc 20 mg/L. Percentage Removal by Modified SB was 98.96% with Cr 6+ conc 20 mg/L, dosage 0.3 g, pH 2, shaking speed 150 rpm, time 180 mints. Hence, the present experimental research concludes that FeCl 3 modified peanut shell powder shows greater Cr 6+ removal efficiency up to 99.97 %.
