The equipment of solid phase micro-extraction with voltage was used to absorb the phenol、nitrobenzene
Abstract: In this artical, the equipment of solid phase micro—extraction was used to adsorb the organic contaminants in the water.. And the adsorb time、voltage、electrolyte solution were considered to discuss whether they got the influence to the adsorbtion. According to the results, the adsorbance of the different benzene derivatives were adsorbed differently. The phenol was adsorbed better under positive voltage, but the nitrobenzene didn’t get so much influenced whether under positive voltage or negative voltage. After added the sodium sulphate solution, the phenol and nitrobenzene were adsorbed much better. So, the equipment can be used in the chemical industry to decrease the adsorbtion cost.
Keywords: the technology of solid phase micro—extraction; gas chromatography; the influence of the electrolyte solution
