Electrochemical detection and quantification of Reactive Red 195 dyes on graphene modified glassy carbon electrode.
Reactive Red 195 was detected from industrial waste samples electrochemically on graphene modified glassy carbon electrode (GCE), using both bare and surface changed GCE at different pH media from 1.0 to 13.0. The optimum pH was determined to be 4.0. RR 195 exhibited good linear responds at pH 4.0 on both electrode surfaces. Other parameters, such as accumulation potential, accumulation time, initial scan potential, pulse height, pulse width, and potential scan increment and scan rate are optimized and calibration plot was also derived on different concentrations of the dye. The stripping voltammetric behavior of dye exhibits very low limit of detection on graphene coated electrode (30 ppb). The adsorption of compound on GCE and graphene coated GCE are confirmed using atomic force microscopy studies.
期刊介绍：
Journal of Environmental Science and Health, Part C: Environmental Carcinogenesis and Ecotoxicology Reviews aims at rapid publication of reviews on important subjects in various areas of environmental toxicology, health and carcinogenesis. Among the subjects covered are risk assessments of chemicals including nanomaterials and physical agents of environmental significance, harmful organisms found in the environment and toxic agents they produce, and food and drugs as environmental factors. It includes basic research, methodology, host susceptibility, mechanistic studies, theoretical modeling, environmental and geotechnical engineering, and environmental protection. Submission to this journal is primarily on an invitational basis. All submissions should be made through the Editorial Manager site, and are subject to peer review by independent, anonymous expert referees. Please review the instructions for authors for manuscript submission guidance.
