Abstract
The determination of inorganic mercury species in water, beverages and foods has been a special research priority in recent years because mercury, as a highly carcinogenic species, even in trace concentration, has high adverse effects on the body of living organisms. In this research, combining two extraction techniques, including microwave‐assisted cloud point extraction and dispersive‐solid phase extraction (MA‐CP‐dSPE), for the separation and pre‐concentration of mercury in environmental samples is presented. This method is based on the dispersion of nanoparticles in micellar media in the presence of a novel mono‐thiosemicarbazone Schiff base (2 N′‐[4‐diphenylamino]benzylidene) hydrazinecarbothiohydrazide) ligand. Using the experimental conditions defined in the optimization, the method allowed mercury determination from 0.020 to 350 mg/L with a detection limit of 0.005 mg/L. The accuracy of the procedure was tested by analysing certified reference material. The method was successfully applied to copper determination in spring water, beverage and rice samples.
期刊介绍:
Water and Environment Journal is an internationally recognised peer reviewed Journal for the dissemination of innovations and solutions focussed on enhancing water management best practice. Water and Environment Journal is available to over 12,000 institutions with a further 7,000 copies physically distributed to the Chartered Institution of Water and Environmental Management (CIWEM) membership, comprised of environment sector professionals based across the value chain (utilities, consultancy, technology suppliers, regulators, government and NGOs). As such, the journal provides a conduit between academics and practitioners. We therefore particularly encourage contributions focussed at the interface between academia and industry, which deliver industrially impactful applied research underpinned by scientific evidence. We are keen to attract papers on a broad range of subjects including:
-Water and wastewater treatment for agricultural, municipal and industrial applications
-Sludge treatment including processing, storage and management
-Water recycling
-Urban and stormwater management
-Integrated water management strategies
-Water infrastructure and distribution
-Climate change mitigation including management of impacts on agriculture, urban areas and infrastructure
