The absorbed benzene hydrocarbon was removed by thermal desorption and directly injected into gas chromatograph and determined by FID detector. It was optimal for the rapid and precise determination of trace benzene hydrocarbon in seawater. In this Paper the investigation of benzene hydrocarbon in the coastal water of Jiaozhou Bay (Qingdao) is reported as well. The data for benzene hydrocarbon are listed in table 3 for 1984 and the station locations are given in figure 6.展开更多
