Determination of Aluminum in Water by Indirect Air -Acetylene Flame Atomic Absorption Spectrometry
摘要
Abstract
It is difficult to determine the aluminum content in water by ordinary air acetylene direct flame atomic absorption spectrometry. Indirect flame atomic absorption spectrometry used in this paper is through copper complex replacement reaction, using air acetylene flame indirectly determines the aluminum content difficult for atomization with excellent experiment effect after separating interference material and low cost for equipment investment and operation. This paper discusses the acidity, solvent, heating temperature, heating time and the static time and instrument parameters effect on the determination of aluminum in water by indirect flame atomic absorption spectrometry, and the interference experiment, detection limit, precision and recovery test, the final results of which meet the requirements of surface water monitoring.关键词
