明胶中硫代硫酸钠含量对氯化银晶体颗粒增长特性的影响

The Effect of Added Sodium Hyposulflte on Growth of Silver Chloride Crystal in Gelatin Solution

1.前言 硝酸银和氨化钠反应生成氨化银晶核,这种晶核逐渐生长,在物理成熟时,这种晶体继续长大,控制反应和成熟条件,达到所需晶体颗粒大小和分布状态。

This work consists of two parts:the first part relates to study of the effect of amount of Na2S2O3 added on physical inhibition of growth by means of UV spectrography; and the second part relates to its effect on the behavior of AgCl crystal growth such as medium particle size, specific surface area and turbidity, using centrifugal particle size analyzer SA-CP3.It was found that the physical inhibition and turbidity were changed with the amount of Na2S2O3 added in gelatin. The former decreases and the later increases with Na2S2O3 increased.
