Flow Injection Spectrophotometric Determination of Sub-mg dm−3 Silver(I) in a Strongly Acidic Solution Containing Concentrated Copper(II) Using a Pyridylazo Reagent

New Spectrophotometric Method for the Determination of Trace Level of Silver Using 2,2'-Di(2,3,4-Trihydroxyphenilazo)biphenyl

“…The method described here has recorded for the first time the non-extractive direct spectrophotometric determination of silver(I) in aqueous media without the recourse of any clean-up step. This method is far more selective, sensitive, non-extractive, simple and rapid than all of the existing spectrophotometric methods [9][10][11][12].…”

Spectrophotometric Micro determination of Silver(I) using Meloxicam as a New Analytical Reagent

“…Therefore, its trace determination in water and environmental samples is important. There are different methods for Ag(I) determination, like , high performance liquid chromatography (HPLC) 6 , atomic absorption spectrometry (AAS) 7,8 , kinetic [9][10][11][12] , capillary zone electrophoresis (CZE) 13 , flow injection analysis (FIA) 14 , fluorimetric 15 and spectrophotometric [16][17][18][19][20][21][22][23][24][25][26][27][28] . Spectrophotometric methods still the most commonly used tools due to the common availability of instrumentation, the simplicity, speed and the accuracy of the technique still make spectrophotometric methods attractive.…”

Analytical application of the reaction system methylene blue B-K2S2O8 for the spectrophotometric kinetic determination of silver in citric buffer media

“…Recently, silver has also been analyzed in ayurvedic and other drugs and medicines, chemical substances, natural and waste water samples, electronics, flow-solders, white metals, ores, alloys, biological samples, etc. [1,3,4] The toxico-kinetics of silver is very complex: its ability to form organometalic compounds and chelate complexes with influence on the metabolic processes in living organisms is subject of investigations in biology and environmental studies.There are different methods for Ag(I) determination, like atomic absorption spectrometry (AAS) [1,2], capillary zone electrophoresis (CZE) [3], fluorimetric [4], high performance liquid chromatography (HPLC) [5], kinetic [16][17][18][19], flow injection analysis (FIA) [20], spectrophotometric [21-28], photometric, etc. Silver was also determined using PVC-membrane electrodes based on 18-crown-6 and dibenzo-18-crown-6 ethers [29].Kinetic methods for Ag(I) determination with spectrophotometric detection, are mainly based on catalytic effect of silver ions upon the reaction rate of oxidation of different reductors by K 2 S 2 O 8 or (NH 4 ) 2 S 2 O 8 [6][7][8][9][10][11][12][13][14][15].…”
