- ... A new adsorbent based on natural clinoptilolite and amorphous zirconium dioxide (ZrO₂) was prepared for the uptake of boron from fresh water. The sorption behaviour of this adsorbent for boron was investigated using a batch system and found to obey Langmuir, Freundlich and Dubinin–Radushkevich (D–R) isotherm models. The ZrO₂ loading level, pH, temperature, contact time, initial boron concentration ...

- ... Cobalt(II) doped chitosan bio-composite was prepared, characterized and used to oxoborate separation from aqueous solutions. The adsorption process was carried out in a batch system. The effect of pH, temperature, time and initial boron concentration on the boron adsorption were tested. The maximum boron adsorption was reached at pH range 8.0–8.5 at room temperature and within 60 min. Calculations ...
