Abstract: Biosorption is a process of using waste biomass to clean contaminated environment. This study was conducted to determine the capability of O. niloticus Linn fish scale as biosorbent for chromium contaminated aqueous solutions. Scales were washed and air dried before exposure to induced-wastewater that simulates high contamination in aqueous solutions. Initial concentration of synthetic wastewater was controlled and final concentration was sent to CRL Laboratory for measurement of total Chromium. Variations on contact time and weigh of dried scales were used to measure the biosorption capabilities of the fish scales where length of exposure used were 24, 48, and 96 hours and weight of dried scales were 1, 3 and 5 grams. Analysis of variance showed significant differences on both length of exposure and weight of biosorbent. Furthermore, the study showed a negative correlation on the chromium-induced wastewater respectively. Moreover, exposure of biomass to highly contaminated aqueous solution showed a drastic decline on chromium concentration with increasing weight of fishscales as well as longer contact times. Future study is highly recommended on the use of O. niloticus Linn and other fish scales on natural heavy metal contaminated freshwater ecosystem.
