Abstract

Adsorption reactions are of utmost importance to understand the availability of nutrients to the plants. The thermodynamic parameters (ΔG^o, ΔH^o and ΔS^o) or the adsorption of manganese on six soils were calculated at two temperatures, i.e., 25 and 35°C. The adsorption data, fitted into the linear form of the Langmuir equation, made it possible to evaluate the adsorption maxima and binding energy. The values of ΔG^o, ΔH^o and ΔS^o were found to be negative in all the soils indicating the exothermic and spontaneous nature of the adsorption reaction.
