英文摘要	Chemical speciation analysis method IS used in the field Of Uranium technology. The method contains two aspects, experimental analysis and theoretical calculation. CHEMSPEC is a newly developed speciation code. In this Work. CHEMSPEC is used to determine the free acid concentration in the presence of uranium(VI) and the conversion channels of UF(6). Three conversion channels are considered: direct hydrolysis, reduction hydrolysis and extraction after F(-) is coupled by Al(3+). The results indicate that the titration endpoint of the acid Solution can be precisely determined by the CHEMSPFC and consist with the results of titration experiments. In the conversion of UF(6), the pH value must be strictly controlled when the direct hydrolysis channel is applied, reduction hydrolysis channel needs suitable reducing agents, while when F(-) is coupled by Al(3+), the extraction channel may applicable in low pH value solutions. These InaV suggest that speciation analysis method could be helpful in the field of uranium technology.
