纸浆和纤维素纳米材料.酸溶性镁钙锰铁铜钠钾的测定

[中文适用范围]： 本文件规定了通过原子吸收光谱法（AAS）或电感耦合等离子体发射光谱法（ICP/ES）测定酸溶性镁、钙、锰、铁、铜、钠和钾的程序。 酸溶成分包括焚烧残渣的酸溶部分，即焚烧后获得的灼烧残渣中可溶于盐酸或硝酸的部分。 在残留物完全溶解的情况下，通过本文件中指定的程序获得的结果是样品中每种元素总量的测量值。 本文件适用于所有类型的纸张、纸板、纸浆和纤维素纳米材料。 测定限度取决于元素和所使用的仪器。 [外文原描述]： This document specifies the procedure for the determination of acid-soluble magnesium, calcium, manganese, iron, copper, sodium and potassium by atomic absorption spectrometry (AAS) or by inductively coupled plasma emission spectrometry (ICP/ES). The acid-soluble element comprises the acid-soluble part of the incineration residue, i.e. that part of the ignition residue obtained after incineration which is soluble in hydrochloric acid or nitric acid. In cases where the residue is completely soluble, the result obtained by the procedure specified in this document is a measure of the total amount of each element in the sample. This document is applicable to all types of paper, board, pulps and cellulose nanomaterials. The limit of determination depends on the element and on the instrument used.
