Leaching Kinetics of Stibnite in Sodium Hydroxide

Spherical pellets of antimony sulphide were dissolved in 1 molar sodium hydroxide solutions at different temperatures. It was found that the shrinking core with ash layer model could satisfactorily explain the dissolution process. Using this model it was found that initially the rate controlling step is a chemical reaction with activation energy of 10.2 kJ/mol. As the ash layer builds up, diffu...

EFFECT OF A CHLORIDE FLUX ON THE DISSOLUTION OF Mn-Al COMPACTS IN MOLTEN ALUMINUM

Abstract: Dissolution and recovery of Mn-Al compacts with and without a chloride flux was studied by taking samples from the melt after addition of the compact. Events occurring after the addition of the compacts into the melt were studied using water quenched specimens after holding them for a specified time in molten state. The cross sections of these specimens were characterized by SEM a...

Effect of Sodium Dodecyl Sulfate on Copper Anodic Dissolution in Phosphoric Acid Solution

In Electrochemical Mechanical Planarization process (ECMP), concentrated phosphoric acid is usually used as electrolyte. Role of sodium dodecyl sulfate (SDS) in anodic dissolution of Cu in concentrated phosphoric acid was studied by Cyclic Voltammetry (CV), inhibition efficiency (IE) calculation and in-situ observation of the Cu electrode surface at anodic overpotentials. It was found that pres...

Effects of calcium hydroxide and sodium hypochlorite on the dissolution of necrotic porcine muscle tissue.

The dissolving effect of the endodontic medicaments calcium hydroxide (Ca(OH)2) and sodium hypochlorite (NaOCl) on necrotic tissue was studied. Pieces of necrotic porcine muscular tissue were placed in either a 0.5% NaOCI solution (Dakin's solution), Ca(OH)2 mixed with water, or a NaOCI solution following pretreatment in Ca(OH)2 for various time intervals. The tissue pieces placed in 0.5% NaOCl...

The effects of sodium hypochlorite and calcium hydroxide on tissue dissolution and root canal cleanliness.

In this in vitro study, we investigated the efficacy of sodium hypochlorite (NaOCl) and calcium hydroxide (Ca(OH)2) in dissolving necrotic tissue and cleaning root canals. In the first part of the study, 0.5% NaOCl solution and Ca(OH)2 paste and solution were tested with samples of necrotic bovine muscle in different treatment modes and for different periods. The necrotic tissue was weighed bef...
