DETERMINATION OF BORON IN STEELS BY ON-LINE FLOW INJECTION CATION EXCHANGE ELIMINATING MATRIX INDUCTIVELY COUPLED PLASMA-ATOMIC EMISSION SPECTROMETRY

摘要

A high performance of system was presented for the determination of boron in steels by on-line flow injection cation exchange eliminating matrix, followed by inductively coupled plasma-atomic emission spectrometry in this paper. The operating parameters were discussed and optimized. 50 mg/ml of iron matrix can be eliminated by the cation exchange column. Two standard steels and four synthetic standards were analyzed. The sensitivity and rate of analysis were improved compared with conventional separation methods. (C) 1996 Academic Press, Inc. [References: 8]
