摘　　要：由透析袋、硒 -铁蛋白、恒流泵、电导仪、磁力搅拌器及电化学系统等构成硒 -铁蛋白电化学反应器。该反应器可储存流动水体中微量含磷化合物于铁蛋白的蛋白壳内,其储存量高低与流动水体中的含磷化合物含量成正比关系。经硒改造后的硒 -铁蛋白能提高有机磷农药的储存量,其储存能力与铁蛋白种类无关,可能与铁蛋白自身构象有关。An Electrochemical reactor of seleno-ferritin consisted of oscillating bag, seleno-ferritin, constant-flow pump, conductivity apparatus, magnetic stirrer, and electrochemical system was used to store the micro- compound containing phosphorus from the flowing water in the protein shell of the ferritin. A positive relation between the content of storing phosphorus from the reactor and its concentration in the flowing water was observed. The storing content of organic phosphate in pesticides increased greatly after the protein was modified by selenous acid. This storing capacity was independent of the kinds of the ferritin, but depended on its conformation.
