Extraction of Sm(III)and Nd(III) with N,N,N’,N’-tetrabutyl-3-oxy-diglycolamidefrom hydrochloric acid

Extraction of Gold(iii) with Mbimtt from Hydrochloric Acid

Extraction - Spectrophotometric Determination of Palladium with Tetrabutyl Ammonium Iodide

A sensitive and selective extraction - spectrophotometric method for the determination of trace amounts of palladium is reported. The method is based on quantitative extraction of brownish tetrabutylammoium tetraiodopalladium (II) ion pair into a small valume of chloroform at pH 1.3-12.0, followed by spectrophotometric measurements. The Beer's law is obeyed over the range 0.02-1.09 <em...

Extraction of Alumina from Local Clays by Hydrochloric Acid Process

A bench work study was carried out to investigate the use of kaolinitic clay containing 29.4% Al2O3 extremely abundant in Saudi Arabia for the production of pure alumina by calcination at 700 o C for 1h (recommended by previous investigators) then leached by hydrochloric acid. The effects of leaching temperature (25 o C to boiling temperature), period of activation (10-150 minutes), acid concen...

The Combination of Edestin with Hydrochloric Acid

Electromotive force measurements of cells without liquid junction, of the type Ag, AgCl, HCl + protein, H(2), lead to the conclusion that 1 gm. of edestin (or, more probably, edestan) combines with a maximum of 13.4 x 10(-4) equivalents of H(+) and 3.9 x 10(-4) equivalents of Cl(-), when the protein is dissolved in 0.1 M HCl.

The Combination of Gelatin with Hydrochloric Acid

1. Cooper's gelatin purified according to Northrop and Kunitz exhibited a minimum of osmotic pressure and a maximum of opacity at pH 5.05 +/-0.05. The pH of solutions of this gelatin in water was also close to this value. It is inferred that such gelatin is isoelectric at this pH and not at pH 4.70. 2. Hydrogen electrode measurements with KCl-agar junctions were made with concentrated solutions...
