Nitrate Removal via a Formate Radical-Induced Photochemical Process

Investigation of Electro-coagulation Process for Phosphate and Nitrate Removal from Sugarcane Wastewaters

Background: Highly-concentrated phosphate and nitrate anions from sugarcane wastewater are often discharged into public waters without standardized treatments. This study assessed the effects of electrical coagulation, initial pH and reaction time in the removal of phosphate and nitrate pollutants. Methods: We used aluminum electrodes to remove the pollutants at Hakhim Farabi Agricultural and ...

Modeling a novel ion exchange process for arsenic and nitrate removal.

Arsenate and nitrate can be removed quantitatively from drinking water by anion exchange. However, if the raw water contains substantial concentrations of sulfate or nitrate, the resin becomes exhausted quickly, and the requirements for regenerant (brine) can make the process unattractive. Previously, we described a modified ion exchange operating procedure for arsenic removal from solutions co...

Knowledge-based development of a nitrate-free synthesis route for Cu/ZnO methanol synthesis catalysts via formate precursors.

High-performance Cu/ZnO/(Al(2)O(3)) methanol synthesis catalysts are conventionally prepared by co-precipitation from nitrate solutions and subsequent thermal treatment. A new synthesis route is presented, which is based on similar preparation steps and leads to active catalysts, but avoids nitrate contaminated waste water.

Comparasion of Photochemical Oxidation Process Efficiency Based on Hydrogen Peroxide and Persulfate for the Removal of Paraquat from Aqueous Solutions

Introduction and purpose: One of the most important factors in the contamination of aquatic ecosystems is agricultural pesticides. Paraquat is a water-soluble and non-selective herbicide, which has adverse health effects, such as respiratory distress and even death. This study aimed to evaluate the degradability of paraquat toxins using photochemical oxidation processes based on hydrogen peroxi...
