The adsorption and mechanism of the nitrification inhibitor nitrapyrin in different types of soils.

ABSTRACT: The nitrapyrin was easily adsorbed by soil, but most current studies have focused on comparing the effects of nitrapyrin application at different soil organic matter levels and in different soil types. The adsorption kinetics and isotherm adsorption of the nitrification inhibitor nitrapyrin in black soil, chernozem and planosol were studied in this paper. The adsorption kinetics were fitted by quasi-second-order kinetic equation (R² ≥ 0.8907, p < 0.05) with a lower acting energy of adsorption (E_a < 8.0 kJ mol^-1). The isotherm was fitted by the Langmuir equation (R² ≥ 0.9400*, p < 0.05). The adsorption mechanism was determined to involve a spontaneous endothermic reaction accompanied mainly b
