“…Therefore, new solutions are constantly being sought to eliminate mercury-based electrodes [70,71]. Mercury electrodes used for trace tin determination include static mercury drop electrode (SMDE) [47][48][49], dropping mercury electrode (DME) [50][51][52], hanging mercury drop electrode (HMDE) [20][21][22][23][34][35][36][37][38][39]51,52], and mercury film electrode (MFE) [40,41]. As you can see, the determination of tin by adsorptive stripping voltammetry has most commonly been carried out using HMDE as the working electrode.…”

“…Suitable electrolyte compositions for electroanalytical methods result in low detection limits and wide ranges of linearity for the method. The most commonly used supporting electrolytes in electrochemical methods have been acetate buffer [24,26,28,29,34,36,[38][39][40][41][42], borate buffer [31], formate buffer [37], hydrochloric acid [30,32,48,[55][56][57], oxalic acid [51], sodium bromide [25], and sodium chloride [33]. For voltammetric methods, acetate buffer was the most commonly used supporting electrolyte [24,26,28,29,34,36,[38][39][40][41][42][43].…”

“…The concentration of hydrochloric acid in the voltammetric methods for the determination of tin was 1.0 mol L −1 . In the case of polarographic methods, hydrochloric acid was used in a concentration range from 0.1 mol L −1 to 3.5 mol L −1 [48,[55][56][57].…”

“…The main advantages of electrochemical methods over other detection systems are that high sensitivities, wide ranges of linearity, and low instrument costs are achieved [19]. Electroanalytical methods for the detection of tin include stripping voltammetry , polarography [47][48][49][50][51][52][53][54][55][56][57], potentiometry [58][59][60], and coulometry [61]. In the literature, most of the works on the electrochemical determination of tin are devoted to voltammetric methods.…”

Tin determination allows for the monitoring of pollution and assessment of the impact of human activities on the environment. The determination of tin in the environment is crucial for the protection of human health and ecosystems, and for maintaining sustainability. Tin can be released into the environment from various sources, such as industry, transportation, and electronic waste. The concentration of tin in the environment can be determined by different analytical methods, depending on the form of tin present and the purpose of the analysis. The choice of an appropriate method depends on the type of sample, concentration levels, and the available instrumentation. In this paper, we have carried out a literature review of electrochemical methods for the determination of tin. Electrochemical methods of analysis such as polarography, voltammetry, and potentiometry can be used for the determination of tin in various environmental samples, as well as in metal alloys. The detection limits and linearity ranges obtained for the determination of tin by different electrochemical techniques are collected and presented. The influence of the choice of base electrolyte and working electrode on signals is also presented. Practical applications of the developed tin determination methods in analyzing real samples are also summarized.

“…19 The NAS calculations are used both for estimation of the figures of merit of an analytical method and its performance including limit of detection, sensitivity and selectivity for each component 26 and for the construction of multivariate calibration models. [20][21][22][23][24][25][26] There are some reports on voltammetric determination of lead and tin by chemometrics methods 12,[27][28][29] and in this paper we develop a simple and new chemometrics method based on differential pulse polarography for simultaneous determination of Sn 2+ and Pb 2+ . With the DPP extremely overlapped peaks was obtained so they was determined by new method called net analyte signal standard addition method.…”

Differential pulse polarography was used for simultaneous determination of Sn 2+ and Pb 2+ . But there is a problem for simultaneous determination and it is high overlapped DPPs of mentioned cations that their determination is impossible in the presence of each other, so multivariate calibration methods as chemomatrics methods were used for this determination. There are some disadvantageous for multivariate calibration methods that can be solved by a new and simple method called net analyte signal standard addition method. This method has some advantages, such as: the use of a full voltammogram, realization in a single step, therefore it does not require calibration and prediction steps and only a few measurements are required for the determination.Keywords: Net analyte signal standard addition method; Simultaneous determination; Differential pulse polarography; Lead; Tin. INTRODUCTIONThe impact of the effects of trace chemical species in the environmental and industrial samples on man's health has fostered development of analytical techniques and instrumentation capable of addressing these issues. 1,2 Different analytical methods were used for simultaneous determination of trace metals like atomic absorption spectrometry, 3,4 high performance liquid chromatography, 5 inductively coupled plasma-mass spectrometry 6 and neutron activation analysis 7 and electrochemical methods. 1,2 Between these methods, one of the reliable, accurate methods that gives qualitative and quantitative information of electroactive species in a sample as a well-known analytical tools with high sensivity and selectivity, coupled with convenience and economy are required. Differential pulse polarography (DPP) has been recognized as a powerful tool for multiel-ement trace metal detection. 2,8,9 In spite of it's high sensivity, this method drawback is the low selectivity. This problem is considerable when our purpose is simultaneous determination of metals and their oxidation and/or reduction potentials are close to each other so there are sever overlapped peaks. In these cases chemomatrics methods are used for analysis of voltamograms and polarograms.
