| 摘 要： | ２４℃下用丙酮提取不同软化度（吸水率）整粒蚕沙的叶绿素ａ和ｂ，测定浸提速率。结果可用新的恒态提取论解释。一级速率常数，叶绿素在蚕沙与丙酮之间的分配系数。软化度由零增至１２０％时，ｋ观与Ｋ分别增大到４．５倍与７．７～１４４倍。

| Abstract: | Measurements have been made of the rate of extraction of chlorophyll a and b into acetone from intact particles of ailk-worm excrements and from the parucles of six different water absorptions at 24℃.These results are interpreted by a new steady-state theory of extraction. The first-order rate constants(kobs) and the parution coefficients(Ks) of chlorophylls between the particles and acetone all increaed dramatically as the water absorptions of the particles increased. |
