3R Potentiometric Membrane for In-Line Environmental Monitoring of Cu2+ in Swimming WaterAuthor(s): Hebatallah M Essam and Mohamed K Abd El-Rahman
The idea of green chemistry has become the most interesting area for research, not only for clean environmental resources but also for whatever we do and however we do. Then, the fundamental goal of green chemistry research is to reduce pouring stream of chemicals for hazards purification. Consequently, the concentration of Cu2+ ions in swimming pools that use Copper ionizers as a disinfectant requires periodic monitoring to be maintained within safe limits. So, a 3R (Reduce cost, waste and solvents, Real time analysis method, Reusable) copper (II) selective electrode with the firstly introduced 2-amino-4-chlorophenol (ACP) was proposed. Confirmatory spectrophotometric study was used to investigate the complex stability and formation ratio between Cu2+ and ACP. Selectivity investigations showed exceptional selectivity for Cu2+ ions over interfering cations in comparison to the usually used sulphur-containing ionophores. The proposed sensor showed successful applications to the in-line determination of copper ions in swimming pools water operated by copper ionization system as a chlorine alternative for disinfection. Statistical studies showed that the suggested technique strategy with such benign design is a superior choice rather than the commonly used off-line technique as atomic absorption that maintains pure planet without the introduction of further hazards into the biosphere.
