We analysed the adsorption of organic phosphorous insecticides and herbicides by ethylcellulose, acetylcellulose, polysulfone, polystyrene and polyvinylchloride using the quartz-crystal microbalance (QCM). Ethylcellulose had a high affinity for both organic phosphorous insecticides and herbicides. The adsorption capacity of acetylcellulos exhabited a low adsorption except for cyanophos.
Polysulfone and polystyrene featured a high affinity for organic phosphorous insecticides and herbicides which polyvinylchloride had low except for fenitrothion. These results indicate that adsorption of insecticides and herbicide by polymers is affected by the chemical structure of the polymers used.
