The use of ion-exchange resins for removal of insecticides from cow milk


, : The use of ion-exchange resins for removal of insecticides from cow milk. Sibirskii Vestnik Sel' skokhozyaistvennoi Nauki ( 2): 72-74

The use of ion-exchange resins to remove residues of organophosphorus acaricides and insecticides from milk is investigated. Because different ion-exchange resins had pHs ranging from 2.0 to 10.2, they were 'trained' to approximately the same initial pH as milk to maximize absorption and to maintain milk quality. This was achieved by washing with solutions of NaOH or HCl, depending on the initial pH of the ion-exchange resins, and then with distilled water, until a pH of 5.9-6.2 was reached.
