铬天青S光度法测定超基性岩石中铝时温度和时间对测定结果影响的探讨

Effect of temperature and time on Determination of aluminum in ultrabasic rocks by chrome azure S Spectrophotometry

超基性岩石中含有大量有用矿物,它已成为地质上寻找铂、镍、铬等金属的重要标志。工业上根据用途的不同需求对超基性岩石组分进行综合评价。铝也是其中需要进行准确测定的成分之一。因铬天青S光度法在测定岩石中铝具有较好的灵敏度,且操作方法相对简便,因此一般常用此法进行测定。但因为此法稳定性较差,需分析人员熟练操作。因此本文着重对此做一些试验和探讨。

Ultrabasic rocks contain a lot of useful minerals.It has become an important symbol for geological prospecting for platinum,nickel and chromium.The ultrabasic rock composition is comprehensively evaluated on the basis of different needs in industry.Aluminum is also one of the components that need to be accurately measured.Because the chrome azure S photometric method has a good sensitivity in the determination of aluminum in rocks,and the operation method is relatively simple,this method is usually used for the determination.However,because of the poor stability of the method,it is necessary for the analytical personnel to operate skillfully.Therefore,this article focuses on doing some experiments and discussions.
