摘    要:原子吸收光谱法直接测定高盐水中痕量镉时,有很大背景吸收和误差。本文采用络合—萃取技术使共存元素与待测元素分离,既消除了基体干扰,又达到了富集作用,使测定结果准确可靠。

关 键 词:高含盐量,背景,络合—萃取,石墨炉原子吸收

Abstract:There is great background absorption and error,when the trace cadmium in high salt water is measured directly with graphite furnace atomic absorption spectromety.This paper proposes a complex extraction technology that could separate the trace cadmium with other elements.This method that removes the base disturbing and concentrates the trace cadmium could make measurement accurate and reliable.
Keywords:high salt water  background  complex extraction  graphite furnace atomic absorption
