Efficiency of Modified Zeolite with Cationic Surfactant Hexadecyltrimethylammonium Bromide in Removal of Diazinon from Aqueous Solutions
Background and purpose: Diazinon is one of the most widely used pesticides in agricultural pest control that pollutes water resources. The aim of this study was to evaluate the adsorption of diazinon from water by zeolite modified with cationic surfactant hexadecyltrimethyl ammonium bromide (HDTMA). Materials and methods: The amount of HDTMA surfactant used to modify the zeolite was one-fold E...
متن کاملRemoval of direct blue 129 from aqueous medium using surfactant-modified zeolite: a neural network modeling
Background: Conserving water for human survival and providing future security are important issues that need to be addressed. Methods: In this study, a zeolite modified with hexadecyl trimethyl ammonium bromide (HDTMA-Br), a cationic surfactant, and its application in removing direct blue 129 (DB129) was examined. Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy...
متن کاملPotential Use of Surfactant-Modified Zeolite for Attenuation of Trace Elements in Fly Ash Leachate
Large volumes of fly ash and other coal combustion products (CCPs) are produced every year by coal-fired power plants. About 50% of the CCPs produced in the U.S. is buried in impoundment lagoons or dry landfills. Fly ash is generally enriched in several potentially hazardous trace elements, such as As, B, Cd, Co, Cr, Mo, Se, Sr, and V, which can leach from older, unlined disposal sites. Therefo...
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 کاملInfluences of clinoptilolite and surfactant-modified clinoptilolite zeolite on nitrate leaching and plant growth.
The increasing demands for environmental protection and sustainable food production require an increase in the use of natural and non-toxic materials for agriculture. In this study, the feasibility of using surfactant-modified zeolite (SMZ) in comparison with zeolite clinoptilolite (Cp) application to reduce nitrate leaching and enhance crop growth was investigated. The effects of size (millime...
