The kinetics of IP6 sorption, pH effects, and sorption isotherms were examined in batch experiments on four desert saline–sodic soils: Antofagasta (AN), Mejillones (ME), Aguas Blancas I (ABI), and Aguas Blancas II (ABII). The sorption kinetics of inositol hexaphosphate expressed as P (P-IP6) on these soils were described by the Elovich equation and the initial sorption velocities ranked in the order: ABII > ABI > ME > AN. In addition, P-IP6 sorption capacity in AN, ME, and ABI was strongly influenced by the solution pH, but in ABII it was not pH-dependent. Whereas the experimental data of P-IP6 sorption on ME, ABI, and ABII were better fitted by the Langmuir equation (implying a homogenous distribution of active sorption sites), for AN the best fit was obtained with the Freundlich model (implying heterogeneous, multi-layered sorption surfaces). The maximum P-IP6 sorption capacities ranked: ABII > ME > AN > ABI. Based on the results of our study, ABII soil is recommended for P-IP6 removal. In this soil, P-IP6 sorption did not depend on solution pH, and the precipitation and sorption of IP6 were associated with Ca2 +, Mg2 +, and minerals such as montmorillonite and vermiculite.}, cin = {IBG-3}, ddc = {550}, cid = {I:(DE-Juel1)IBG-3-20101118}, pnm = {246 - Modelling and Monitoring Terrestrial Systems: Methods and Technologies (POF2-246) / 255 - Terrestrial Systems: From Observation to Prediction (POF3-255)}, pid = {G:(DE-HGF)POF2-246 / G:(DE-HGF)POF3-255}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000340315700055}, doi = {10.1016/j.geoderma.2014.06.016}, url = {https://juser.fz-juelich.de/record/172073}, }
