Abstract:In order to accurately obtain photometric information of high concentration SO42− and other substances in the process industry, the spectroscopy behavior of SO42−, S2−, Ni2+ and Cu2+ in air and nitrogen atmosphere was compared based on the UV-visible spectrophotometer with a nitrogen replacing the oxygen. Different from Ni2+ and Cu2+, the accuracy of SO42− and S2− in the ultraviolet region was effectively improved by using a nitrogen atmosphere (P detection results were regressed within the limited standard ra… Show more
The dilemma of activity and stability limits the application of metal-based anodes in electrooxidation, especially in concentrated acid media, and thus causes the emission of hazardous wastewater and waste. Herein,...

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
