Synthesis of Sodium Lauryl Sulfate (SLS) and Hexadecyltrimethylammonium Bromide (HDTMA-Br) Surfactant-Modified Activated Carbon as Adsorbent for Pb2+ and NO3-

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...

Preparation and Characterization of Activated Carbon derived from olive stone as adsorbent for Congo Red

Carbon activated powdered was prepared from activated carbon derived from olive stone. Then byusing the surface methodology, many parameters such as pH, furnace temperature (T), acid ratio,time of activation that affect on the qualities prepared activated carbon produced and its efficiencywere investigated. In addition, the adsorption of Congo Red onto the activated olive stone carbonactive was...
