微波消化在磷矿石样品制备中的应用

Application of Microwave Digestion for Sample Preparation of Phosphorous Ore

摘要: 以微波ＨＮＯ＿３消化分解磷矿石试样，用ＩＣＰ－ＡＥＳ进行多元素同时测定。该方法经磷矿石标准样品验证后，用于云南省九个地区磷矿中Ｃａ、Ｐ、Ｆｅ、Ａｌ、Ｍｇ和Ｋ六种元素的分析，结果与经典酸分解方法制备样品的分析结果相符；同一样品平行测定９次，其各元素的相对标准偏差（ＲＳＤ）在１．５８％～４．４１％。

Abstract: The sample was dissolved in HNO_3 by microwave digestion and the solution obtained was analyzed by ICP-AES. The method has been tested on standard reference materials.Phosphorus ores collected from nine regions of Yunnan were analyzed for Ca,P,Fe,Al,Mg an
