Abstract:
By ICP-AES, we established a method to quantitatively determine the micro-elements in couplers. We processed the unknown sample with wet digesting method. Nine micro-elements in the couplers can be quantitatively determined at the same time. Using the powerful chem.-station, we have discussed the method to eliminate physical interference and background correction. The results of the experiment showed that the method is accurate, quick, of high performance, and with all RSDs < or = 1.00%. The linear correlation coefficient of the tested elements is over 0.9999.
