The important feature of the thermal gravimetric analysis is quantitative and can accurately measure the change in mass of the substance and the rate of change, it can be said that it can be used the thermal gravimetric analysis to study the change process as long as the change in materials’ weight took place when they were heated [5-7].
The water loss of the two materials basically no longer change after 5h, that is, the PCB water loss rate neared 1.3%, and the CCL water loss rate was close to 0.8%.
Table 3 PCB and CCL cumulative water loss rate derivative h Types 1 2 3 4 5 PCB 0.108 0.068 0.052 0.035 0.030 CCL 0.072 0.063 0.009 0.012 0.009 It can be seen from Table 3 that the derivative of PCBs and CCLs weightlessness took on downward trend, which showed that the change of moisture in the material was getting smaller and smaller, and the derivative of the two materials’ weight loss is close to zero after 4h.

Preconcentration of Arsenic in Radix aucklandiae by Sulfhydryl Cotton and Determination by Atomic Fluorescence Spectrometry Qingshan Pan, Wei Liua, Heping Yan, Bo Zhou, Baosen Wang, Shijuan Xu School of Science, Honghe University, Key Loboratory of Natural Pharmaceutical & Chemical Biology of Yunnan Province Mengzi, Yunnan 661199,P.R.
Sulfhydryl cotton contains a lot of thiol, thiol can adsorp Hg2+, As2+, Cd2+, Cu2+, Ag+ and other metal ions, it is a good metal ions preconcentration and separation materials[4-5], enrichment of metal ions and can be separate by thin hydrochloric acid.
Arsenic Standard Solution：100mg/L (National Research Center of Standard Materials of China)；Standard working solution of Arsenic: the arsenic standard solution was diluted step by step by 5% hydrochloric acid solution to 1mg/ as the working solution, arsenic standard solution and working solution were placed in the refrigerator to save .All above reagents were guaranteed reagent.
