【Abstract】 Trace amount of Hg co precipitated with Cu 2HgI 4 and Cu 2I 2 was determined by use of solid phase reflection diffuse spectrophotometry. In this paper, basic principle of the analysis was discussed and optimum conditions for reaction and analysis were determined by experiment. This method features rapid and simple, showing high sensitivity and versatility in determining trace amount of Hg in soil, water and plant, as well as in the air of polarographic laboratory.更多还原
