标准范围

本文件规定了基于湿化学和电感耦合等离子体发射光谱(ICP-OES)的方法，用于非生物医学应用的磷酸钙基粉末的化学分析，例如化学工业、空气、水和土壤污染的处理。它规定了磷酸钙基粉末的主要元素及其杂质的测定方法。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。使用沉淀法和重量法或ICP-OES法测定磷含量。通过ICP-OES方法测定某些杂质，例如铝、钡、铬、铜、铁、镁、锰、镍、钾、硒、硅、钠、锶、钛和锌含量。本文件不包括用于生物医学应用的磷酸钙基粉末。ISO？13779系列使用各种方法表征生物医学应用的羟基磷灰石粉末，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）。

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).
