Extraction of Titanium(IV)–Pyrocatechol Violet Complex with Tridodecylethylammonium Bromide

Palladium Ternary Complex with Chromeazurol S and Cetyltrimethylainmonium Bromide and Cetylpyridinium Bromide

Formation of green coloured ternary complexes between palladium, chromeazurol S and cetyltrimethylammonium bromide or cetylpyridinium bromide is described over the pH range 4.6 to 5.6. The compositions, Pd(CAS)CTA2 and Pd(CAS)CP2 for the ternary complexes have been established by Job's method of continuous variations and by the mole ratio method using absorbance data. Strict control of experime...

Synthesis of Triethyl Propargyl Ammonium Bromide from Triethyl Amine With Propargyl Bromide

The reaction between trimethylamine with propargyl bromide was studied and the structure of triethyl propargyl ammonium bromide was illustrated by 1HNMR, IR, and Mass spectra.

Uranium Extraction from Solid Waste as Nitrate Complex with D2EHPA, TOPO and their Synergistic Mixture

Ion Pair Dispersive Liquid-Liquid Microextraction for the Determination of Trace Amounts of Copper(II) in Soil, Multivitamin Tablet, Tea and Water Samples Using Flame Atomic Absorption Spectrometry

Ion pair dispersive liquid- liquid microextraction (IP-DLLME) method combined with flame atomic absorption spectrometry was proposed for the determination of trace amounts of copper(II). By using pyrocatechol violet as chelating agent and cetyltrimethyl ammonium bromide as an ion pairing agent, the trace amount of copper(II) was extracted in chloroform. The factors influencing the formation cop...

A Novel Magnetic Nano-hybrid as a Sorbent for Solid-phase Extraction-spectrophotometric Determination of Methyl Violet 10B Dye

In this research, the magnetite polystyrene maleic anhydride (MPSMA) was synthesized and structure and morphology characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy techniques. The obtained nano-structured inorganic material was employed as a novel magnetic nanosorbent for separation and pre-concentration of Methyl violet (10B) dye from aqu...
