Utilization of treated coffee waste as adsorbent for heavy metal (Cadmium, Chromium and Lead) removal from synthetic water

In this study, treated coffee waste was used to remove heavy metals (Cd, Cr and Pb) from synthetic water. For the adsorption studies, operational parameter such as adsorbent dosage and contact time were studied. For the characterization, Fourier-transform infrared spectroscopy (FT-IR) and Scanning e...
