《GB/T 5121.7-2008铜及铜合金化学分析方法 第7部分:砷含量的测定》由TC243(全国有色金属标准化技术委员会)归口,TC243SC2(全国有色金属标准化技术委员会重金属分会)执行,主管部门为中国有色金属工业协会。
GB/T5121《铜及铜合金化学分析方法》共有27部分。本部分为第7部分。本方法规定了铜及铜合金中砷含量的测定方法。本方法适用于铜及铜合金中砷含量的测定,测定范围:0.00005%--0.0010%。本部分代替GB/T5121.7―1996《铜及铜合金化学分析方法 砷量的测定》和GB/T13293.5―1991《高纯阴极铜化学分析方法 砷钼杂多酸�步峋ё戏止夤舛确ú舛ㄉ榱俊贰1静糠钟耄牵拢�T5121.7―1996、GB/T13293.5―1991相比,主要变动如下:
―――方法一是对GB/T13293.5―1991的修订,采用“氢化物发生�参奚�散原子荧光光谱法”代替原标准“砷钼杂多酸�步峋ё戏止夤舛确ā保�
―――方法二是对GB/T5121.7―1996的修订,补充了质量保证和控制条款,增加了精密度条款;

Scope
This method specifies the method for the determination of arsenic in copper and copper alloys. Method 1 Hydride generation - non-dispersive atomic fluorescence spectrometry: measurement range: 0.00005% ~ 0.0010%. Method two blue spectrophotometry: measurement range: > 0.0010% ~ 0.10%. Method Three photometric method: This method is suitable for the determination of arsenic as an alloying element or impurity arsenic in copper and copper alloys listed in ISO international standards.
