Electrochemical Properties and Antibacterial Activity of Polyvinyl Chloride Supported Silver Molybdate Ion-Exchange Composite Membrane
Polyvinyl chloride supported silver molybdate composite material is used to develop by solution casting method. This membrane was characterized by various instrumental techniques such as Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA) and scanning electron microscopy (SEM) analyses. These characterizations are used to understand the functional groups,thermal sta...
متن کاملA colorimetric reaction of chloride ion.
Specificity of Reactions-Several alkaloids were tested for their reaction with chloride, bromide, and iodide ions. The test system was as follows: From 0.01 to 0.05 milliequivalent of the halogen compound (sodium salt) was placed in calorimeter cuvettes. Water was added to make a volume of 5 ml. and then 2 ml. of 50 per cent phosphoric acid were added. 1 ml. of a 1 per cent solution of the alka...
متن کاملRapid and Sensitive Determination of Trace Chloride Ion in Drinks Using Resonance Light Scattering Technique
A resonance light scattering (RLS) technique to determine chloride ions in drinks was developed. Chloride ions were found to bind Ag(+) forming AgCl aggregates that produced intense resonance scattering light. Effects of factors such as acidity, ionic strength, and coexistent interferents on the RLS of AgCl aggregates were investigated. The pH of solution almost did not affect the production of...
متن کاملSensing of Iron Ions by Solid Phase Spectrophotometry
A new sensitive and selective spectrophotometric method for the determination of iron using a PVC membrane containing bathophenanthroline and dioctylphethalate as the solid phase extraction medium is investigated. Fe(II) in an aqueous sample solution is trapped on the membrane with an anion species, picrate ion and forms a complex with bathophenanthroline. The absorbance of the red-orange m...
