摘要: 氯化银{100}面T 颗粒乳剂是一种新型感光乳剂,近年来受到感光界广泛关注.本文着重讨论了明胶中蛋氨酸含量对该种乳剂生成过程的影响.实验发现,明胶中蛋氨酸含量对乳剂微晶的晶体形态和形成一定晶形的乳化时间的长短有直接影响,并推断这一作用与蛋氨酸对颗粒表面Ag+的吸附密切相关.

关键词: 蛋氨酸, 氯化银, T-颗粒, 吸附作用

Abstract: The high chloride tabular grain emulsions exhibit a good many of advantages and this kind of emulsion has already become a main branch in the field of the study of silver halide emulsions.The present paper uses some modified gelatin with low Met. content at different preparation processes of emulsions in order to develop the suitable condition for the growing of the tabular grains with {100} faces.

Key words: Methionine, silver chloride, T-grains, adsorption effect
