Determination of polonium by dithizone extraction

Selective Cloud Point Extraction and Preconcentration of Copper by the Use of Dithizone as a Complexing Agent

The aim of this work was to develop a selective cloud point extraction method for the separation and preconcentration of copper(II) prior to spectrophotometric determination. For this purpose dithizone was used as a complexing agent and the experimental solution was acidified with sulfuric acid. Triton X-114 was used as a surfactant and after phase separation, based on the cloud point of th...

Determination of mercury at a dithizone-modified glassy carbon electrode by anodic stripping voltammetry.

Extraction of Fig Leaves to Synthesize of Ag Nanoparticles for Determination of Atorvastatin by Spectrophotometery

In this method, firstly, extracts of Fig tree leaves are taken with a simple laboratory method, and then the research begins on a very important drug in medical science. The effects of different variables such as pH, volume and type of buffer, volume of nanoparticles and time of stay were investigated. The results showed that optimal amounts of pH = 6, 1.5 mL citrate buffer, 0.15 mL optimum vol...

Determination of Iron Species by Combination of Solvent Assisted-Dispersive Solid Phase Extraction and Spectrophotometry

A simple, rapid and sensitive solvent assisted-dispersive solid phase extraction method was developed for the extraction of iron(II) prior to its spectrophotometric determination. The Fe(II) reacted with 2,4,6-tris(2-pyridyl)-1,3,5-triazine, neutralized with sodium dodecyl sulfate and extracted onto the fine particles of benzophenone which were formed upon rapid injection of a mixture of benzop...
