| Abstract: | The condition which determioes wavelength, the numbers of wavelength and the numbers of calibrated mixed solution were studied in simultaneous determination of mult icomponent by CPA Matrix method in this paper, and it proposes four selecting rules. The results shows that the above conditions have a great effect OP the calculating results. The results of determining simul taneously nitrite and nitrate mixture sgstem by CPA matrix method satisfied the requirement of micro-analysis. |
