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.

A robust and parsimonious model for caesium sorption on clay minerals and natural clay materials. Applied Geochemistry, Elsevier, 2017, 87, pp.ABSTRACT 12 Caesium (Cs) is one of the most studied radionuclides in the fields of nuclear waste disposal 13 and environmental sciences. The overall objective of this work is to improve the tools designed to 14 describe and predict migration, retention, and bioaccumulation processes in the geosphere and the 15 biosphere, particularly in the soil / solution soil / plant roots systems. Cs sorption on clay minerals 16 has been extensively measured and modelled because these minerals control Cs mobility and 17 (bio)availability in the environment. 18A critical analysis of published experimental data on Cs sorption by clay minerals and 19 natural clay materials along with the different models was performed in an attempt to elaborate and 20 evaluate a generic model for Cs sorption. This work enabled us to propose a robust and 21 parsimonious model for Cs sorption, which combines the surface complexation and cation 22 exchange approaches invoking only two types of surface sites: frayed edge and exchange sites. Our 23 model, referred to as the "1-pK DL/IE model", takes into account the competition between Cs and 24 *Revised manuscript with no changes marked 1999) and the principal source of radioactivity of nuclear waste in the timeframe of the first one 48 hundred years. Moreover, radiocaesium always exists as the monovalent cation Cs + , with chemical 49
