Abstract
Purpose
Biochar amendments can alter phosphorus (P) availability in soils, though the influencing mechanisms are not yet fully understood. This work investigated the adsorption and desorption of P on ferrihydrite (F, a Fe-oxide widely distributed in surface environments) in order to evaluate the interactions between P and Fe-oxide in the absence or presence of biochar (F or ferrihydrite–biochar (F–B) interaction) in soils.
Materials and methods
Biochar was produced by pyrolysis of rice straw at 600°C in steel ring furnaces. Two-line ferrihydrite was synthesized by dropwise addition of 1 mol L−1 KOH into Fe(NO3)3 solution until the pH reached 7–8 while stirring vigorously. An F–B complex was prepared under similar conditions, except that a mixture of 10 g biochar and the Fe(NO3)3 solution was used as the starting material instead of Fe(NO3)3 alone. A batch equilibration method was used to determine sorption or desorption of P. The mechanisms of P adsorption on F and F–B complex materials were discussed.
Results and discussion
Adsorption of P on F decreased as the pH was increased from 3.0 to 10, but the adsorption capacity of F decreased by about 30–40% in the presence of biochar. The P chemisorption rates on F also decreased in the presence of biochar. The Freundlich model showed that the active adsorption sites on the surface of the F–B complex were energetically heterogeneous. The desorbability of adsorbed P on F was enhanced by combination with biochar. The mechanisms of P adsorption on F and F–B complex materials are different.
Conclusions
The results showed that the amount and rate of P adsorption on the surface of ferrihydrite decreased with the presence of biochar, and the desorbability of adsorbed P on ferrihydrite can be enhanced when combined with biochar. Thus, the presence of biochar can decrease P adsorption on the Fe-oxides and enhance P availability in soils.
