Abstract:
... 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 ...
