纯净单矿物试样不易获得,按本文介绍的步骤,可在10mg试样中,对锰单矿物和脉石进行连续四元素测定,与常规法测定结果对照,尚能符合。 一、试剂与仪器 锰、铁、镁均用纯金属配制,钙为氧化钙保证试剂配制,盐酸,硝酸为优级纯试剂,其他为分析纯试剂。 微量分析天平,湘西天平仪器厂,分度值0.1mg。 Pure single mineral sample is not easy to obtain, according to the steps described in this article, in the 10mg sample, the manganese single mineral and gangue continuous four element determination, compared with the conventional method of determination, still can meet. First, the reagents and equipment Manganese, iron, magnesium are made of pure metal, calcium is guaranteed reagent preparation of calcium oxide, hydrochloric acid, nitric acid is excellent grade pure reagent, the other is analytical reagent. Micro analytical balance, balance instrument plant in Xiangxi, sub-value 0.1mg.
