| Abstract: | The absorbed Pb in diatomite filter aids was extracted by diluted HCI, and determinated by inductively coupled plasma atomatic emission spectrometry(ICP-AES). The influence of extraction time, extraction temperature, extracting agent concentration and ratio of diatomite (g)/extracting agent(mL) was studied. The RSD is 2.78%-6.29%,the recovery is from 96.0% to 103.3%, and detection limit is 0.026μg/mL. The method is accurate, simple, rapid for the determination of adsorbed Pb in diatomite filter aids. |
