A nanocellulose-based adsorbent was successfully synthesized via a hydrothermal process. It characterized by X-ray diffraction, Fourier Transform Infrared Spectroscopy, Field Emission Electron Microscopy and Brunauer–Emmett–Teller surface area analysis. Photocatalysis has the best potential to replace conventional wastewater treatment technology through photodegradation of organic contaminants....

conclusions briefly, the current study represents a novel method to eliminate temephos as an organophosphate compound from water samples with modified zero-valent iron nanoparticles. background temephos is an organophosphate pesticide used as larvicide in the environment. although not extremely hazardous, it can be risky for human health in the moderate concentrations. objectives this study inv...

Used fly ash as raw material, it was modified by acid, alkali and high temperature to produce adsorbent, sulfuric acid sodium hydroxide adsorbent adsorbent. In this paper, the effects of dosage, adsorption time, initial dye concentration, wastewater pH on were studied. The results showed that: had a good treatment effect dye; when dosage 1.00 g, time 90 min, 4, 45 °C, decolorization rate 60 mg/...

sawdust is now being investigated as an adsorbent to remove contaminants from aqueous solution. heavy metals can be decreased very effectively with the organic material. in this research, adsorption of pb (ii) onto modified beech sawdust in a batch system was investigated. sawdust was collected from timber mill of qom, iran, and modified with h2so4 and naoh. then, the effects of various paramet...

Experiments were carried out to evaluate the batch adsorption of sulfur compounds from petroleum refinery wastewater on a chemically modified activated carbon (MAC). The modification technique enhances the removal capacity of carbon and therefore decreases cost-effective removal of sulfide from refinery wastewater. Different techniques have been used to characterize the modified activated carbo...
