Investigation of the Effect of Lead Adsorption on Surface Modified Fish Bones

Abstract

This study investigates lead (Pb) elimination of surface modified fish bones as a biogenic apatite source. Surface modification was performed with 4-Aminohippuric acid (MBA1) and 2-Thiophenecarboxaldehyde (MBA2). In this study, different methods were used for surface modification. Apart from that, lead elimination was performed by the method of adsorption in aqueous solution. It is detected that both of the modified materials eliminate as 7.16 mg/g in 50 mgL-1 lead solution. It was determined that MBA1 and MBA2 materials removed 99.9% of the lead in solution. In conclusion, it is seen that waste fish bones, which are regarded as worthless, can be applied to the chemical modifications and they can be transformed into useful materials. It is possible to say that transforming them into economic, efficient, qualified and useful materials can contribute environment.
