The absorption spectrum of yellow phosphorus within ultraviolet area was tested. the method to determine yellow phosphorus in water and wastewater using ultraviolet spectrophotometry analysis, which need no acidation and oxidation, and can colorimetric determination directly.
试验了黄磷在紫外光区的吸收光谱 ,建立了紫外分光光度法测定水和废水中黄磷的方法。
参考来源 - 水和废水中黄磷的测定CO conversion is 95% and 100% and the yield of formic acid and dimethyl carbonate is 90% and 85% respectively. These technologies provide the basis for purifying the yellow phosphorus tail gas to produce C1 chemistry products.
这2个工艺既利用了黄磷尾气,又无三废排放,其一氧化碳的转化率分别为95%和100%,甲酸和碳酸二甲酯的收率分别达到90%和85%,为净化黄磷尾气合成多种一碳化工产品提供了工艺基础。
