河仓棒酸钠（alendronatesodium）是骨质疏松症和Paget病治疗剂。介绍感应耦会等离子体（ICP）法测定其磷含量的方法，该法快速、精密、准确。阿仑律酸钠三水合物的浓度为O031mg·mL－‘时的相对标准差为1．95％，含相当于4Omg和2．5mg阿仑棒酸盐游离酸的片剂的相对标准差分别 Alendronatesodium is a treatment for osteoporosis and Paget’s disease. The method of determining the phosphorus content by inductively coupled plasma (ICP) is introduced. The method is rapid, precise and accurate. The relative standard deviation of sodium alanate trihydrate at O031 mg · mL- ’was 1.95%, and the relative standard deviations of tablets containing equivalent of 4O mg and 2.5 mg of aleuronic acid free acid were
