Sensitive adsorptive stripping voltammetric method for determination of lead in water using multivariate analysis for optimization

Microelectrode Arrays with Overlapped Diffusion Layers as Electroanalytical Detectors: Theory and Basic Applications

“…The lowest detection limit of all electroanalytical techniques corresponds to electrochemical stripping analysis [118–120]. It is widely used for determination of metal ions and halides in water, food, biological fluids and environmental samples [121–123].…”

ADSORPTIVE STRIPPING VOLTAMMETRIC METHODFOR THE INDIVIDUAL DETERMINATION OFCd(II), Cu(II), Pb(II), AND Zn(II) IN VEGETABLESAMPLES USING CALCEIN

“…Selectivity can be improved by choosing a selective ligand and an electrolyte solution. The detection limit is lowered by increasing the concentration of the analyte adsorbed on the working electrode surface electrodes [20][21][22][23] . Several ligands have been used for the determination of trace metals simultaneously is 8-quinolinol 26 , xylinol orange 24 , calcon 7,9 , and alizarin [15][16] The use calcein as a complexing agent in AdSV ever done for titanium 24 , aluminum and gallium 22 .…”

Optimization of composite admixtures used in cementation formula for radioactive evaporator concentrates

“…PlacketteBurman design, introduced by Plackett and Burman in 1946, is a useful statistical tool to optimize multi-variable problems based on factors effects analysis with few experiments (Plackett and Burman, 1946). PlacketteBurman design has been proven to be time-andeffort-saving in various areas including hazardous wastes treatment (Arain et al, 2008;Espada-Bellido et al, 2009;Kamarei et al, 2010;Singh and Dikshit, 2010). However, when a multi-variable system has more than one response to optimize, PlacketteBurman design becomes less satisfactory.…”
