Benzalkonium Bromide Cationic Surfactant Removal from Wastewater Using Magnetite Nanomaterial

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...

Removal of Tetracycline Antibiotic from Aqueous Solution Using Zeolite-X Modified by Pyridium Bromide Cationic Surfactant: A Laboratory Study

Background and Objectives: Antibiotics are among the pollutants that have entered uncontrollably in the environment, and lead to serious environmental problems such as disrupting aquatic ecosystems, and causing health problems for humans and other organisms.  Therefore, it is necessary to remove them from the environment. In the current study, zeolite modified by cationic surfactant of cetylpyr...

Applications of Magnetite Nanoparticles for Heavy Metal Removal from Wastewater

Magnetic Solid Phase Extraction and Removal of Five Cationic Dyes from Aqueous Solution Using Magnetite Nanoparticle Loaded Platanusorientalis Waste Leaves

This paper reports on synthesis of a magnetic adsorbent for wastewater treatment purposes. In this regard, platanus orientalis waste leaves were chosen as a cheap material for preparing the magnetic adsorbent by loading magnetite nanoparticles on it. The synthesized adsorbent was characterized using scanning electron microscope and X-ray diffractometer. Then, it was used for magnetic solid phas...

Removal of Cationic Dyes from Aqueous Solution using Organomodified Nanoclay

In this work, organomodified nanoclay has been used as the adsorbent for the removal ofbasic blue 41, cationic dye from an aqueous solution. The performance of the organomodified nanoclay was tested in a batch system under varying pH (2–12), adsorbent dosage (0.1–2 g L-1), initial dye concentration (10–60 mgL-1), and contact time (5- 100 min). The best conditions were achieved at pH of 7,...
