Findings from Xinjiang Technical Institute of Physics and Chemistry Update Knowledge of Sulfur Amino Acids (Highly Efficient Co-removal of Heavy Metals in Wastewater from Chemical Oxygen Demand Testing Instrument by Cysteine-functionalized ...)
By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Sulfur Amino Acids have been published. According to news originating from Urumqi, People's Republic of China, by NewsRx correspondents, research stated, "Wastewater discharged from chemical oxygen demand(COD) testing instrument was generally difficult to treat due to its high content of heavy metals and very low pH. In this study, a kind of cysteine-functionalized magnetic narioparticles(MNPs-Cys) was synthesized and used to treat the wastewater."
Our news journalists obtained a quote from the research from the Xinjiang Technical Institute of Physics and Chemistry, "The synthesized MNPs-Cys as the adsorbent for heavy metal removal from aqueous solutions were systematically investigated. The adsorption dynamic process fit the Langmuir isotherms well with a maximum adsorption capacity of 76.92 mg/g for Cu(II). The adsorbent could be easily regenerated by 0.1 mol/L HNO3, which exhibited a high adsorption performance within 10 cycles. This adsorbent, combined with a developed pretreatment approach, could make Cr(III), Hg(II) and Ag(I) in the wastewater discharged from COD testing instrument effectively removed and the removal efficiency is more than 99%."
According to the news editors, the research concluded: "This work gave a new insight into the design and synthesis of high-performance materials for treating wastewater with heavy metals."
