摘要：

This work aimed to study the biosorption of metal ions by chitosan beads, conducted at room temperature by adding chitosan beads into a conical flask containing different initial pH. The flask was agitated, and the concentrations of metal ions were determined using inductively coupled plasma-optical emission spectrometry (ICP-OES). It was found that the sorption percentage and capacity on the effect of pH for metal ions increased with pH and hit a plateau at pH 3 for single-metal solutions, while binary-metal solutions hit a plateau at pH 2. A consideration separation of Au(III) from Cu(II) could also be achieved at pH 3-5.
