Investigation of the Effect of Sorbent Dosage and Solution pH on the Adsorption Efficiency of Catfish- and Tilapia-Derived Hydroxyapatite

Abstract:

The contamination of water by heavy metals is still a continuing threat to the surrounding environment and to the lives of those exposed to it. A group of techniques to remove ions from contaminated water may employ naturally occurring sorbent materials like hydroxyapatite (HA). HA was successfully extracted from waste fishbones of locally-sourced catfish and tilapia as shown by the diffractograms. The amount of ions removed from Pb²⁺ solutions at two pH levels using 30 and 60 mg HA powders were determined using Atomic Absorption Spectroscopy. Based on the data, increasing pH and HA dosage increased the adsorption efficiency for both types of HA. However, the saturation of HA has not been attained with calculated adsorption capacities decreasing further with sorbent dosage due to an increase in the number of adsorption sites for a limited amount of ions. Although the values obtained at this level are comparable for both catfish- and tilapia-extracted HA, further studies will be needed to measure their corresponding maximum adsorption capacities. With this investigation, wastewater treatment for lead (II) ion contamination may become more accessible using inexpensive raw materials.
