| Summary: | The Malacca River, a vital water resource, faces a critical challenge posed by escalating high level of nickel and other heavy metals pollution. As the adverse effects of this contamination on both aquatic ecosystems and human health become increasingly evident. The research objectives aimed to validate the best geopolymer pellet for polluted river water remediation. Hydrothermal method was employed for synthesis process of geopolymer and curing process was employed to form concrete geopolymer pellets. SEM/EDX and ICPMS characterization employed, to analyse the pore size and heavy metal absorption capacities of the geopolymer pellets. Water samples from the Malacca River were initially analysed to establish baseline of heavy metal concentrations. Subsequently, geopolymer pellets with varied compositions were immersed in the water samples to analyse heavy metal content before and after immersion using ICPMS. This research used Inductively coupled plasma mass spectrometry (ICP-MS) to detect the presence and concentration of selected heavy metal. Findings revealed distinct variations in heavy metal absorption capacities among different geopolymer pellets, with promising results in reducing contamination levels. The successful synthesis of a geopolymer material, enhanced with coconut husk, underscores its potential as an eco-friendly remedy for mitigating heavy metal contamination. The results show significant removal efficiency of nickel heavy metal. The best geopolymer pellet is the geopolymer pellet with addition of 3% coconut husk which demonstrated the highest removal efficiency, indicating enhanced porosity from coconut husk addition facilitating heavy metal absorption by the geopolymer pellet |
