【摘要】 <正> 关于混合磷酸盐的分离及其测定,国外文献虽有报导,但材料较少。国内尚未见有关报导。据现有资料介绍,采用的方法有红外光谱法,化学分析法,纸上层析法。用的较多的是纸层析分离后分光光度法测定,但从分离到测定过程繁杂而再现性差。随着材料科学的发展,特别是由于小型激光器的发展,磷酸盐激光材料的研制引起人们高度重视后,对混合磷酸盐的分离和测定就提出了更高的要求。为了满足磷酸盐激光材料研制的需要,我们根据混合磷酸盐体系中不同种直链多磷酸盐在有机相和水相中分配比的不同,对用纸层析法分离和测定混合磷酸盐作了进一步的研究,通过反复实验,对分离用的纸形和展开的方式,对定量用的试剂和测定的条件更多还原

【Abstract】 Dueto the development of the microlaser, More attentions have been paid to the study and preparation for phosphates laser materials. During the preparing changes of solution constituents have large effect on growth of the crystal. If the changes of system have to be clarified, separation and determination of phosphate system are necessary.Though there are reports on foreign litertures about the separation and determination of mixed phosphats, they are less, So far no reports about the same subject are published in our country. In order to satisfy the need of preparation of the phosphates laser materials, the author makes further approach in separating and determining the mixed phosphates, A simpler,swiftter,accurater analytical method has been renovated through repeated experiments.The method is to make use of guantitative filter paper or slightly cut it out, then add sample, To make use of acidic solvent one-time level development, or first alkaline solvent and then acidic solvent two-time level development,it is depending on quantity of the highpolymerizated acid contained in the sample. Then color-developing agent is added to the rinse solution of the chromatogram, and such mixedsolution is heated, hydrolysised, color-developed, determined by spectrophotometer.Analytical results of large guantities of samples show that the method described by this grticle not only apply to the analysis of the solution constituents in the growth of the phosphates crystal, but also has common signficance for separation and determination of the other phosphates system.更多还原
