| Popis: | This work was aimed at the study of clinoptilolite zeolite as sorbent of Ni(II) from aqueous solutions. Sorption and desorption studies were performed in batch for natural purified, and NH3, NaCl and NaOH treated zeolites at the following optimized conditions: pH 5, sorbent dose of 4 g·L−1, contact time of 30 min and room temperature of 30 ± 2 0C. Sorption capacity increased with the sorbent, as follow: NH3-treated zeolite (9.9 ± 0.6) |
