查询词典 distillation

After the research of anodic oxidation slag, we got the composition of the suspension electrolyte of zinc sulphate solution. 2 The results of electrode kinetic of anodic oxidation showed that the electron transfer during the process of electrochemical oxidation was 1, and the electrochemical mechanism was: ZnS=Zn~(2+)+S~-+e Zn~(2+)+2S~-=ZnS + S~0 3 The flow sheet which can produce zinc according to suspension electrolysis principle in industry was put forward. 4 Elemental sulfur in oxidizing slag was recovered by distillation.

本文的创新点是： 1提出了以硫酸锌溶液为基础的悬浮电解液体系；通过对阳极氧化渣进行系统的分析研究，得出了硫化锌矿物的悬浮电解的电解液组成； 2通过阳极氧化电极过程动力学分析得到，电化学氧化过程中电子转移数为1，电化学机理为： ZnS=Zn~(2+)+S~-+e Zn~(2+)+2S~-=ZnS+S~0 3提出了工业上利用悬浮电解原理生产金属锌的工艺流程； 4对氧化渣中的元素硫采用蒸馏法原理进行回收。

By using the direct distillation principle, an improved and quick method which can determine the protein content in maize, soybean meal, rapeseed meal, fish meal, wheat bran, formula feed for swine and formula feed for chicken was established. The result of the study on 142 products belonging to 7 kinds of feedstuffs in three laboratories suggested that: the DD method has fine correlation with the National Standard Method. The relative deviation of the two methods was in conform to the National Standard. The coefficient of variation between different laboratoies was lower than 3%, the coefficient of variation within single laboratory was lower than 2%.
