Abstract:
Iranian researchers from Islamic Azad University, Shahreza Branch, increased the efficiency of the removal of nickel (II) toxic ion from aqueous solutions by modifying clinoptilolite nanozeolite.

Modified Nanozeolite Boost Efficiency of Nickel Removal from Wastewater

Tehran, Iran | Posted on February 2nd, 2014

In addition to removing nickel from wastewater, the researchers also succeeded in simultaneous synthesis of a material with catalytic properties.

The researchers firstly converted clinoptilolite zeolite particles into micrometric particles (MCP) through mechanical methods, and then converted the particles into nanoparticles (NCP). In order to eliminate probable impurities caused during the milling process and also the impurities dissolved in water, they refluxed the obtained powder in addition to suspending stirring with magnet by using magnetic stirrer. Then, they made contact between NCP and DMG alcoholic solution and they prepared NCP exchanger modified with DMG ligand (NCP-DMG).

In this research, DMG - a selective ligand for nickel ion - was used to modify zeolite nanoparticles. During the process, an adsorbent with desirable selectivity for nickel was obtained as well as increasing the adsorption capacity of nickel by zeolite.

In this research, sorption efficiency and selectivity of the adsorbent towards nickel ion were increased by modifying nanozeolite particles with dimethylglyoxime ligand, and a catalyst was obtained as co-product. The use of natural zeolite as the bed is among the characteristics of the research because it is available, cost-effective, and accessible.

The adsorbent produced in this method can be used in the removal of nickel ion from wastewaters of industries such as cell-fabrication, plating, and so on. The sorbent can be used as a catalyst in partial oxidation of some alcohols after adsorption of nickel.

Results of the research have been published in Journal of Hazardous Materials, vol. 260, 15 September 2013, pp. 339-349.
