| Abstract: | Methylmercury in water,sediment and soil samples is preconcentrated onto a sulphydryl cotton adsorbent and analyzed by capillary column GCECD.A comparison is made about analysis of methylmercury between capillary column and packed column.The results show that the detection limit of capillary column analysis is 05pg,but packed column is 2pg.The precision of capillary column analysis is also superior to packed column.The operation condition of preconcentration is researched.The best condition obtained is 35 for pH of sample solution and 2ml/min3ml/min for flow rate. |

| Keywords: | methylmercury capillary column packed column sulphydryl cotton adsorbent analysis |
