“…The authors suggest that their modelled citrate effect only occurs on 32 soils where adsorption is influenced by phyllosilicate clays. In this comment we report that 33 this conclusion is the result of a series of unfortunate data and modelling errors, which mean 34 that the modelling exercise of Duputel et al (2013) is completely wrong. 35 The work of Duputel et al (2013) builds on the modelling approach of Devau et al (2014).…”

“…In their recent paper Duputel et al (2013) predict using a multi-site surface complexation 24 model that citrate can decrease inorganic phosphorus (P) solubility in the presence of 25 common soil minerals. Duputel et al (2013) even suggest, that "special attention should be 26 given to microbiologically-mediated citrate degradation in order to avoid the risk of 27 obtaining an adverse effect of citrate adsorption on available P".…”

Recently, the high‐concentration phosphorus‐containing wastewater has been caused lots of negative influences on aquatic environment and thus driven people to develop some effective methods to remove excess of phosphate in water. In order to solve these environmental problem, in this work, a tetraethylenepentamine (TEPA) modified 4A zeolite has been prepared and used for removing phosphate. Removal of phosphate by precipitation of 4A zeolite and electrostatic action of TEPA with phosphate were determined by scanning electron microscopy, X‐ray powder diffraction and Fourier infrared spectrum, and morphology and characteristic peak of TEPA‐4A zeolite before and after adsorption changed significantly. In addition, the results of batch adsorption studies showed that the pH of the solution have a significant influence on the adsorption of TEPA‐4A and the biggest adsorption capacity was 23 mg/g at pH = 2.3 ± 0.2. Adsorption isotherms results showed that the process was consistent with Langmuir model and the maximum adsorption capacity could reach to 28 mg/g at 25 °C. TEPA‐4A adsorption processes were spontaneous endothermic reaction, and elevated temperatures were conducive to the adsorption process through kinetics and thermodynamics results. The research of TEPA modified 4A zeolite and raw 4A zeolite provides technical support for the development of 4A zeolite instead of sodium tripolyphosphate as a new type of detergent ingredient.

Surface complexation models have proved to be valuable tools for predicting processes that occur at the solid-solution interface. Use of such models has become more widespread and nowadays more complex systems are studied, in an attempt to explain processes such as the competition between different species for mineral surfaces and the effect of the presence of organic matter. The aim of the present study was to analyze the mobility of phosphate in ferralic soils. The charge distribution model parameters for phosphate-goethite adsorption were used to predict phosphate mobility on samples from 2 horizons of a ferralic soil containing large amounts of iron oxides. The soil reactivity was attributed to the iron oxides, and some specific parameters were determined by means of phosphate adsorption-desorption experiments and included in the model. Adsorption of phosphate in the upper horizon, which contained more organic carbon and phosphate than the deeper one, was modeled by using the information obtained for the soil and the charge distribution model parameters derived for phosphate-goethite interaction with no need of further optimization. In contrast, some extra fitting parameters were required to improve the modeling of the phosphate adsorption in the deeper horizon.
