Daftar Isi:
- Chemistry laboratory generally produces heavy metal waste which must handle carefully and cannot be vanished directly into watercourse consequently need the third party to handle it. Third party will calculate the cost based on the total volume or does not based on concentration, therefore enrichment is needed to reduce the cost. Solid phase extraction was chosen as enrichment heavy metal process. There was several step to optimize the extraction ability such as cross-linker agent, pH, contact time, metal concentration before it can be applied to heavy metal laboratory waste. As solid phase extraction, chitosan was made as chitosan beads adsorbent by reacting with tripolyphospate. After chitosan beads formed, it became brownish beads by crosslinking with glutaraldehyde (GLA) and flake chitosan beads by crosslinking with epichlorohydrine (ECH). From IR spectra, there was 2 signature peaks of tripolyphospate at 1640 cm-1 and 1540 cm-1 and there was not difference peaks between GLA or ECH chitosan beads. Optimization by varying cross-linker agent showed chitosan beads ECH 5% adsorbed highest amount of metal Pb until 19,71%±0,8 and can be proceeded for other optimization process.
