A new Method for the Removal of Ammonium from Drinking Water Using Hybrid Method of Modified Zeolites / Catalytic Ozonation
Introduction: Ammonia in form of ammonium ions is toxic and could decrease the dissolved oxygen in water and endanger the aquatic life. The aim of this study is the removal of ammonium using oxidation and adsorption by catalytic ozonation and clinoptilolite zeolite, respectively. Methods: The research method is Experimental. First, optimal pH of ammonium adsorption on carbon catalyst (5 g/L), ...
متن کاملSurfactant Modified Zeolites –adsorbents for Mycotoxins and Carriers of Drugs
The potential of surfactant modified zeolites as adsorbents for mycotoxins and as carrier of the pharmaceutical drugs was investigated. Ochratoxin A OCHRA (mycotoxin) and diclofenac sodium DS (anti-inflamatory drug) were used as model substances. Surface of the clinoptilolite was modified with different amounts of quaternary ammonium ions (hexadecyltrimethyl ammonium HDTMA or octadecyldimethylb...
متن کاملEvaluation of Surfactant-modified Zeolite for Control of Cryptosporidium and Giardia Species in Drinking Water
Gastrointestinal infection due to biological contamination of drinking water supplies is a major health issue worldwide. Naturally occurring and inexpensive modified materials such as surfactant-modified zeolites (SMZ) have net positive surface charge, which may prove useful for adsorption of pathogens such as Cryptosporidium parvum and Giardia intestinales (lamblia). SMZ is engineered by modif...
متن کاملArsenic Removal Using Iron-modified Zeolites
We determined the ability of two iron-and-zeolite materials to remove arsenic from groundwater. The first material is composed of iron, surfactant-modified zeolite, and hard silicate foam, and is known as Surfactant-Modified Zeolite/ Zero-Valent Iron (SMZ/ZVI). The second material is a new formulation that consists of iron-modified zeolite (IMZ). We prepared eight different prototypes of IMZ fo...
متن کاملNitrate Removal from Drinking Water using Organo-Silane Modified Natural Nano-Zeolite
Nitrate-containing compounds are considered as groundwater contaminants, the concentration of whichhas been growing in these resources during recent years. As a result, it seems necessary to use effectivemethods to remove nitrate from water and wastewater. Adsorption is generally considered moreeconomical in water treatment compared to other feasible a...
