| 摘 要： | 铝和铝试剂(玫红三羧酸铵)在微酸性溶液中形成深红色素,在一定范围内,其颜色的深浅与待测液中铝含量成正比关系,借此测定铝的含量。对相关技术指标进行分析,结果表明:本方法检测浓度低,分析结果稳定可靠,能满足饮料中微量铝的分析要求。

| Abstract: | Dark red pigment is formed when aluminum or aluminum reagent (rose tricarboxylic ammonium )is put into slightly acid solutions. Within a certain range, the chroma is positively correlated with the aluminum content in the solution. In this way, the aluminum content is determined. The relevant technical indices were analyzed. The results showed that this method could produce stable and reliable results, and therefore it could be used to analyze the trace aluminum in beverages. |
