分光光度法测定砂MB值的试验研究

Experimental study on spectrophotometry determination for MB value of sands

试验用分光光度法测定砂MB值的可行性。对比传统色晕法和分光光度法测定的结果,证明分光光度法测得的MB值较色晕法略高,但其测量精度优于色晕法。两种方法测得的结果存在强烈的相关性,可采用回归的公式进行相互换算。

Test the feasibility of sand MB values measured by spectrophotometry determination. Comparing the results of two methods to prove that MB value obtained by spectrophotometry determination is slightly higher than the traditional determination, but its measurement accuracy better. There is a strong correlation between the results obtained by the two methods, they can be translated to each other by obtained regression formula.
