(一)一般概述 H_2O_2法測定錳:是最为便捷之方法,对于锰矿及其治炼产品均能适用。本法对高含量尤称适宜,1%以下的低含量亦较ZnQ法测定准确。所存在的问题是,试样中的有机物不能被酸分解,须用碳酸钠处理。此不被酸分解的黑色残渣中锰的含量虽极微(0.01—0.4%),但足以引起误差,所以低含量试样不宜采用此法。用ZnO法测定锰,已不能适应地质工作的跃进新形势,故而我们试用H_2O_2法来测定锰,以改变我们在工作上的被动局面,经数次试验,所得结果与ZnO法非常相近。茲将我们试验结果,简述如下,供大家参考讨论。使此法更趋完善。
(A) General Overview H_2O_2 method for the determination of manganese: is the most convenient method for manganese ore and its refining products can be applied. This law is particularly appropriate for high levels, low levels below 1% are also more accurate than the ZnQ assay. The problem is that the organic matter in the sample can not be acid decomposition, to be treated with sodium carbonate. This is not acid decomposition of the black residue in the content of manganese is minimal (0.01-0.4%), but enough to cause errors, so the low content of the sample should not use this method. The determination of manganese by ZnO method can not adapt to the new situation of leaping in geological work. Therefore, we use H_2O_2 method to determine manganese to change the passive situation in our work. After several experiments, the results are very similar to those of ZnO method. We will test the results, outlined below, for your reference. Make this law more perfect.
