精细陶瓷（先进陶瓷、先进技术陶瓷） 非生物医学应用磷酸钙基粉末的化学分析方法

[中文适用范围]： 本文件规定了用于非生物医学应用（例如化学工业、空气、水和土壤污染处理）的磷酸钙基粉末的化学分析的湿化学和电感耦合等离子体发射光谱法（ICP-OES）方法。它规定了用于测定磷酸钙基粉末及其杂质的主要元素的方法。磷酸钙基粉末通过酸分解而分解。使用滴定法或ICP-OES法测定钙含量。使用沉淀和重量法或ICP-OES法测定磷含量。某些杂质，例如铝、钡、铬、铜、铁、镁、锰、镍、钾、硒、硅、钠、锶、钛和锌含量，通过ICP-OES法测定。本文件不包括用于生物医学应用的磷酸钙基粉末。各种方法，例如原子吸收光谱法（AAS）、电感耦合等离子体质谱法（ICP-MS）和火焰原子吸收光谱法（FAAS）。 [外文原描述]： This document specifies wet chemical and inductively coupled plasma–optical emission spectrometry (ICP–OES)-based methods for the chemical analysis of calcium-phosphate-based powders for non-biomedical applications, such as those in the chemical industry, the treatment of air, water and soil contamination. It stipulates the methods used for the determination of major elements of calcium-phosphate-based powders and their impurities. Calcium-phosphate-based powders are decomposed by acid decomposition. The calcium content is determined using a titration method or an ICP–OES method. The phosphorus content is determined using a precipitation and gravimetric method or an ICP–OES method. Certain impurities, such as aluminium, barium, chromium, copper, iron, magnesium, manganese, nickel, potassium, selenium, silicon, sodium, strontium, titanium and zinc contents, are determined by an ICP–OES method. This document does not include calcium-phosphate-based powders for biomedical applications. The ISO 13779 series characterizes hydroxyapatite powders for biomedical applications using various methods, such as atomic absorption spectrometry (AAS), inductively coupled plasma–mass spectrometry (ICP–MS) and flame atomic absorption spectrometry (FAAS).
