摘　　要：在定性、定量分析的基础上,利用KCl的化学特性,将植物吸收钾肥的过程反演。解析出造纸碱回收过程中危害物质的反向形成机理,并通过实验取得了这种物质——ClK6,在理论计算基础上界定了ClK6的结构,与实际得到的物质片层结构相符合;在去除ClK6的多种工艺中筛选出一种最为合理高效的工艺,并合成了LHA试剂,LHA试剂对ClK6有特殊的去除效果;通过实验得到了去除Cl-和K+的效能值FX(X=KCl～ClK6),FX可表征LHA试剂对KCl～ClK6的去除率,并可判定所得KCl～ClK6的纯度为工业级、试剂级、钾肥级。In the qualitative,quantitative analysis on the basis of the use of KCl chemical properties.Life is engineering,the process of plant K inversion,analyze the paper industry in the process of the alkali recovery hazards of reverse formation mechanism,and through the experiment made this substance—and the calculation basis of defining the structure,and the material actually gets slice layer corresponds with the structure.In a lot of the screening process to remove a the most reasonable and efficient technology,and the synthetic reagent,have a special effect to remove.And got removed and the efficiency of the value,it can find the FX,the purity of KCl^ClK6 for industrial,reagent grade,K fertilizer level,reuse,recycle.
