“…The methodologies for mercury analyses in water samples are complex, need expensive equipment and require qualified operators. Taking into consideration all the above aspects, our attention was focused on a voltammetric technique suitable for mercury detection and quantification of their concentration in water samples involving the experiences of our colleagues from the oldest university in Iasi and in Romania [21].…”

Water pollution demands emergency actions for better water resource management to respect the concept of sustainable development. The aim of the Water Framework Directive, as long-term water policy of the European Union, is to assure the good quality of surface waters. Each state from Europe has to identify all the river basins lying within their national territory and to assign them to individual river basin districts. In this respect, an effective integrated system and monitoring technology, analysing, interpreting data and utilizing the results to make decisions related to the water resources protection, were developed. The main objectives are focused on the expansion of monitoring activities and obtaining more detailed information on the state of surface waters. Specific recommended equipment which enables to perform the analysis of recommended water quality parameters should be placed on the monitoring stations of the Lower Danube "asin. Respectively, this lack of equipment provides a challenge in the development of effective methodologies for collection and analysis of water quality data. The main priority was the development of an integrated water catchment area management strategy and to build up the online continuous monitoring system. Some of the technical goals for continuous water monitoring were reached in Hungary and Romania and are presented here.

Abstract:In the present work voltammetric investigations have been performed on HgCl 2 aqueous solutions prepared from a Cz 9024 reagent. Carbon paste electrode (CPE), eriochrome black T modified carbon paste electrode (MCPE/EBT) and KCl 1M as background electrolyte, were involved within the experimental procedures. Cyclic voltammetry (CV) has been performed in order to compare the behaviour of the two electrodes in both K 3 [Fe(CN) 6 ] and mercury calibration aqueous solution. Differential pulse anodic stripping voltammetry (DPASV) was used to determine the most suitable parameters for mercury determination. All experiments were performed at 25 ± 1 °C, using an electrochemical cell with three-electrodes connected to an Autolab PG STAT 302N (Metrohm-Autolab) potentiostat that is equipped with Nova 1.11 software. The measured potential values were generated by using the silver chloride electrode (AgClE) as reference and a platinum wire electrode as auxiliary. A series of time depending equations for the pre-concentration and concentration steps were established, with the observation that a higher sensitivity can be obtained while increasing the pre-concentration time. DPASV were drawn using the CPE in 11.16 % coriander, as mercury complex, the voltamograms signals indicating mercury oxidation, with signal intensity increasing in time.
