Emulsions of the four insecticides and a herbicides fenitrothion, isoxathion, cyanophos, and trifluralin were diluted with water, physiological saline, or artificial gastric juice to produce standard solutions of the various concentrations. The capacity of the five polymers polyleucine, polyphenylalanine, nylon 12, poly (glutamic acid amide), and ethyl celluiose to adsord solutions of the higher concentrations was evaluated. The capacities of adsorbin and active carbon, both for use in medicines, were compared with the capacities of the polymers. The dependence of adsorption on the concentration of the agents was studied. The strength of the solvents to decrease the adsorption by polymers was, from strong to work artificial gastric juice, physiological saline, and water. The adsorption by the polymers of a nonionic surface-active agents was less than their adsorption of the agricultural chemicals. Coexisting surfactants did not interfere with the adsorption of the chemicals by the polymers, especially polyleucine and polyphenylalanine, but did interfere with the adsorption by active carbon.
