    Examining adsorbent charge effect on metal removal from contaminated water
    (David Publishing, 2022) Agwaramgbo, Lovell; Alisa, Christopher O.; Doyle, Jailen
    Heavy metal contaminated water sources can cause serious health problems for humans, animals, and plants. Heavy metals can lead to the decrease or loss of liver, kidney, and brain function. Objective: The aim of this research is to examine the effect of charge on adsorbents in the removal of metal cations. Study Design & Methods: Standard solutions of Ca, Cu, Pb, and Zn with concentrations of 1,000 ppm were treated with sodium carbonate and sodium phosphate with various charges. Then, the solutions were placed on a shaker for 24 h, centrifuged, and the supernatant was analyzed using ICP-AES (Inductively Coupled Plasma-Atomic Emission Spectrometry). Results: The order of average metal removal by sodium phosphates is: dibasic (99.3%) > monobasic (96.5%) > tribasic (95.4%). The average metal removal by sodium carbonate and bicarbonate is 98.5% and 96.4% respectively. Conclusion: The adsorbent removability depends on the relationship between the charge present on the metal and the charge on the adsorbent. Thus, metal cations in this study with a +2 charge had a greater affinity for the adsorbent with -2 charged ligands, dibasic sodium phosphate and sodium carbonate.
