Synthesis of Chitosan from Calappa pustulosa Shell for the Removal of Heavy Metals in Borehole Water in some Selected Basic Schools in Effia-Kwesimintsim Metropolis in the Western Region of Ghana

The heavy metal contamination of borehole water in basic schools is a serious environmental problem in the Effia Kwesimintin Metropolis, Sekondi-Takoradi in the Western Region of Ghana. This research looked at how well synthetic chitosan worked as an adsorbent to remove heavy metals from borehole water in a sample of elementary schools. With maximum adsorption capacities of 93.5, 87.5, and 67.5% for lead, cadmium and arsenic respectively, the findings showed that chitosan had a high adsorption capacity for these metals. The adsorption data were well-fitted to the linear Langmuir isotherm model indicating monolayer adsorption, with maximum monolayer coverage (Qmax) of the synthesized chitosan, the Langmuir constant (KL), the Langmuir separation factor (RL) and R2 values were found to be 59.3356mg/g, 0.01931/mg, (35.3E-03 – 771.0E-03) and (0.9945-0.9973) respectively. The study demonstrates the potential of synthesized chitosan as a low-cost and sustainable adsorbent for the remediation of heavy metals from borehole water in some selected basic schools
