The efficiency of modifying the Ukrainian clinoptilolite-containing rocks to improve their adsorption and catalytic properties was evaluated based on data XRD, IR spectroscopy, low-temperature N2 adsorption, testing in micropulse transformation C6-hydrocarbons. effect such modification distribution reaction products established.

Batch and column experiments were conducted to evaluate the efficiency of a clinoptilolite zeolite as an inexpensive sorbent material to remove cationic surfactant from water. With an initial surfactant concentration greater than its critical micelle concentration, the removal of surfactant is achieved by admicellar sorption onto the zeolite surface. Although the sorption capacity of hexadecylt...

The present investigation has been carried out to assess a chromium, cobalt, and cadmium from wastewaters by natural and modified zeolites were examined by using batch type method. A clinoptilolite type synthetic / natural zeolite were pretreated with HCl and HNO3 to improve the adsorption capacity for heavy metals. The removal efficiencies and kinetics of heavy metals such as chromium, cobalt ...

Ion exchange properties of five different Japanese natural zeolites in seawater were examined. Sodium ions could be reduced by all zeolites, although anions, Cl(-) and SO(4)(2-), in seawater showed barely changes. Natural zeolite desalination treatment mainly depends on the ion exchange between Na(+), K(+) and Mg(2+) in seawater and Ca(2+) in natural zeolite. This study found that mordenite ...

The research focuses on ammonia and phosphate removal from wastewater by using a novel metal microwave-treated clinoptilolite. For increasing adsorption capacity, the samples were calcinated or microwave irradiated in solutions of Fe(III), Cu (II), Ca(II) chlorides. BET-specific surface area measurement revealed that calcination led to decrease 18.254 11.658 m2/g. results fitted theoretical mod...

The purpose of this study was to evaluate the effect of natural clinoptilolite (NCLI) and modified clinoptilolite (MCLI) on broiler performance, gut morphology, and its relation to gut circumstances. A total of two hundred forty 1-d-old male chicks were randomly assigned to 3 treatments, each of which comprised 8 pens of 10 chicks per pen. Birds in the control group were fed the basal diet, whe...
