[ 1 ] - Determination of Acidity Constants of p-Rosolic acid and Bromoxylenol Blue by Solution Scanometric Method
Recently solution scanometry, as a new, simple, fast, portable, and economic method was introduced for determination of acidity constants of indicator and dyes. In this study, a method was applied for the determination of the acidity constant of p-Rosolic acid (RA) and Bromoxylenol blue (BXB) indicators. The method is based on scanning of Plexiglas® sheet containing colored solutions with a fla...
[ 2 ] - Determination of Erythrosine in Food Samples by CPE-Scanometry as a New Method And Comparison with Spectrophotometric Results
In this study, the trace amounts of erythrosine, as a food dye is determined by cloud point extraction-scanometry (CPE-Scanometry) as a new, facile, available, fast, sensitive, and low cost method. The method is based on the CPE of analyte from aqueous solution, diluting the extracted surfactant-rich phase with ethanol, transfer to Plexiglas®cell and scanning the cells containing the...
[ 3 ] - Al(III) Coated Wire Selective Electrode Based on 5-Bromo(salicylidene-2-aminothiophenol) Schiff Base as a New Ionophore
A new Al(III) selective membrane based on 5-bromo(salicylidene-2-amino thiophenol) as a neutral carrier in a poly(vinyl chloride) (PVC) matrix is coated on platinum wire to determine trace amounts of Al(III) ion in various samples. The sensor exhibits a good response for Al(III) ion over a wide concentration range of 5.20 × 10-7 to 1.00 × 10-2 M with Nernstian slope of 19...
[ 4 ] - Kinetic and thermodynamic studies of the removal of murexide from aqueous solutions on to activated carbon
The objective of this study was to assess the adsorption potential of activated carbon (AC) asan adsorbent for the removal of Murexide (Mu) from aqueous solutions. The influence of variablesparameters including pH, amount of adsorbent, sieve size of adsorbent, temperature and contact timeon Mu removal was studied. Following optimization of variables, the relation between concentrations ofdye re...
