“…Cadmium originates from various sources such as plastic, fossil fuels, metal companies, fertilizers, and cesspit. It is a trace element, which is easily taken and enters into food chain (Jain, 2004), might hinder the intake of nutritive elements such as zinc (Charles et al, 2001). The level of cadmium in Maruf Dam was found to be 0.21 μg/L.…”

Abstract:In this study, the preliminary findings obtained from 3 sampling points, which represent the whole, on Maruf Irrigation Dam, which is located in Boyabat district of Sinop province, for 12 months between September 2015 and August 2016 were examined. The parameters monitored are temperature, dissolved oxygen, pH, electrical conductivity, total hardness, total alkalinity, chemical oxygen demand, biological oxygen demand, and dissolved anions and cations (sodium, potassium, calcium, magnesium, ammonium, nitrate, phosphate, chloride, sulfate, and sulfite). Because of its low dissolved ionic matter content, Maruf Dam was characterized as an alkali dam with mid-hard water and low electrical conductivity. In terms of parameters A and B of Surface Water Quality Management Regulation, the dam is considered "high-quality" and "unpolluted". Besides the irrigation purposes, for which the barrage was constructed, the dam can also be used for aquaculture, animal breeding, and farming needs.

“…A small baseline drift was observed during the analysis and corrected by a linear adjustment of the baseline before and after the elution peak. The results for SLEW-2 and NASS-5 obtained after this linear correction are given in [8].…”

The paper describes an integrated luminometer able to perform £uorescence (FL), room temperature phosphorescence (RTP) and chemiluminescence (CL) measurements on seawater samples. The technical details of the instrumentation are presented together with £ow injection (FI) manifolds for the determination of cadmium and zinc (by FL), lead (RTP) and cobalt (CL). The analytical ¢gures of merit are given for each manifold and results are presented for the determination of the four trace metals in seawater reference materials and Scheldt estuarine water samples.

“…Notable approaches make use of solution-phase chelation followed by adsorption onto reversed-phase C 18 substrates [1,2,3,4,5,6,7,8,9], activated carbon [10,11] or PTFE knotted reactors [12,13,14,15], retention on chelating resins [16,17,18,19,20,21,22,23,24,25,26,27,28], precipitation [29,30,31,32], and electrodeposition [33,34]. The on-line methods exhibit some favorable features over the manual batch-type procedures, such as fully automated sample treatment, lower risk of contamination, and direct coupling with the detection system.…”

“…The on-line methods exhibit some favorable features over the manual batch-type procedures, such as fully automated sample treatment, lower risk of contamination, and direct coupling with the detection system. Therefore, since 1980 there has been a significant increase in the number of papers dealing with on-line preconcentration as well as the number of sorbent materials proposed for the separation of trace metals from complex matrices [16,17,18,19,20,21,22,23,24,25,26,27,28,35,36]. Iminodiacetic resins, such as Chelex-100 and Muromac A-1, have been widely used to concentrate heavy metals from aqueous samples, since they are able to strongly bind the heavy metals with adequate sorption kinetics [37].…”

Determination of ultratrace elements in natural waters by solid-phase extraction and atomic spectrometry methods

et al. 2003

A study was carried out on the preconcentration of ultratrace amounts of cadmium, lead, manganese, copper and iron from high-salinity aqueous samples and determination by atomic spectrometry methods. Sample volume, amount of resin, loading flow rate, and elution volume were optimized in order to obtain the simultaneous preconcentration of all the analytes. Quantitative recoveries were obtained by using 200 mg of iminodiacetic resin with a loading flow rate of 2 mL min(-1), elution volume of 3 mL and sample volume of 50-450 mL. Only copper in seawater samples was not completely retained by the resin (60-70% recovery), due to unfavorable competition of iminodiacetic-active groups with organically bound metal.To quantify the metals in the eluates, two atomic spectrometry techniques were compared: electrothermal atomization atomic absorption spectrometry (ETAAS) and inductively coupled plasma-optical emission spectrometry (ICP-OES) with simultaneous CCD detection system. Both techniques are suitable for sample analysis with detection limits of 1.0, 4.7, 3.3, 6.8, and 53 ng L(-1) using ETAAS and 12, 122, 3.4, 17, and 21 ng L(-1) using ICP-OES for Cd, Pb, Mn, Cu, and Fe, respectively. Relative standard deviations of the procedures ranged from 1.7 to 14% at the sub-microg L(-1) concentration level. The accuracy of both methods was verified by analyzing various certified reference materials (river water, estuarine water, coastal and off-shore seawater).
