标准范围

这些方法适用于“可溶性”锑含量在0.05%（m/m）至5%（m/m）范围内的涂层材料。在发生争议的情况下，应使用AAS法作为仲裁方法。火焰原子吸收光谱法的原理是将试验溶液吸入乙炔/空气火焰中。用锑空心阴极或锑放电灯测量选定线的吸收。罗丹明B分光光度法的原理是用二异丙醚从强盐酸溶液中氧化后提取锑。与罗丹明B溶液形成红色络合物，并在约553 nm波长下分光光度测量颜色。

The methods are applicable to coating materials having "soluble" antimony contents in the range of about 0,05 % (m/m) to 5 % (m/m). The AAS method should be used as the referee method in cases of dispute. The principle of the flame atomic absorption spectrometric method consists in aspiration of the test solution into acetylen/air flame. measurement of the absorption of the selected line, amitted by an antimony hollow-cathode or antimony discharge lampe. The principle of the Rhodamine B spectrophotometric method consists in extraction of the antimony after oxidation from strong hydrochloric acid solution with di-isopropyl ether. Formation of a red complex with Rhodamine B solution, and spectrophotometric measurement of the colour at a wavelength of about 553 nm.
