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...
متن کاملOn the Aging of Ferrous Hydroxide and Ferrous Carbonate
Interest in the aging of metal hydroxide has increased greatly during the past few years and it is due, no doubt, mainly to the fact that certain metal hydroxides have become useful for the isolation of enzymes and vitamins. The selective adsorption properties of these hydroxides, aluminum hydroxide for example, make them suitable for these purposes. Their surface forces make it possible to sep...
متن کاملPrecipitation of reactive aluminium hydroxide from an acidic aluminium sulphate solution by addition of sodium hydroxide
The goal of the present thesis was to study the possibilities of producing an aluminium hydroxide, which would easily dissolve in hydrochloric acid. Furthermore, the product should be easy to dewater. In the experiments, which were made batch-wise, a 50% sodium hydroxide was used to accomplish the precipitation. The precipitation of aluminium hydroxide is a dynamic process that depends on many ...
متن کاملBiosorption of Uranium (VI) from Aqueous Solution by Pretreated Aspergillus niger Using Sodium Hydroxide
The removal of uranium and any other heavy metals from wastewater might be achieved via several chemical or physical treatment techniques. Biosorption process has been considered as a potential alternative way to remove contaminants from industrial effluents. Moreover the surface of biosorbent was characterized by SEM. The biosorption characteristics of uranium (VI) on pretreated A...
متن کاملOptimization of Chemical Texturing of Silicon Wafers Using Different Concentrations of Sodium Hydroxide in Etching Solution
In this paper, the morphology of chemically etched silicon with various concentration is reported. The surface of Silicon (100) has pyramidal structures which can be used for anti-reflection applications in solar cells. Pyramidal structures can capture incident sun light therefore can enhance the efficiency of silicon solar cells. The structure of silicon pyramid was studied using scanni...
