Paper, board and pulps — Determination of cadmium content — Atomic absorption spectrometric method 纸、纸板和纸浆——镉含量的测定——原子吸收光谱法
发布日期: 2013-07-29
ISO 10775:2013规定了一种测定所有类型的纸、纸板和纸浆中痕量镉的方法,包括含有再生纤维的产品,这些产品可以按照ISO 10775:2013的规定在硝酸中湿法燃烧。 测定下限取决于所用设备,通常约为10μg/kg。在本试验条件下不溶于硝酸的颜料和填料中的镉可能无法定量测定。
ISO 10775:2013 specifies a method for the determination of traces of cadmium in all types of paper, board and pulp, including products containing recycled fibre, that can be wet-combusted in nitric acid as specified in ISO 10775:2013. The lower limit of the determination depends on the equipment used and is normally about 10 μg/kg. Cadmium present in pigments and fillers that do not dissolve in nitric acid under the conditions of this test may not be determined quantitatively.
