摘要
对含氟电气石单矿物金分析中氟对铝的影响及电气石中化合水的测定条件进行了试验,证实在F-存在下用铬天青S光度法测定铝,结果严重偏低,改用KF取代-EDTA滴定法可获得满意结果。对电气石中化合水的测定条件进行了对照,并对矿物中的杂质元素进行了分析,保证了结果的准确性。
<Abstrcat>The affection of Fluorine on Aluminum in individual mineral of fluoric tourmaline is studied in this paper.It is confirmed that the results of A1 will be definitely lowered by Chrome azurol S spectrophotometric method while there is F in the solution.If the method of KF replacement-EDTA complex metric titration is applied,the results will be better.The determination of combined water by Penfield tube gravimetry were tested conditions in different.The accuracy of total analysis results is guaranteed impurity in the mineral is determined.
