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 کاملGermicidal Efficiency of Sodium Hydroxide, Sodium Carbonate, and Trisodium Phosphate ^
In this paper the writers present results which they obtained, for the most part, in making a comparative study of disinfectants that, might be used by poultrymen, a fact which accounts for the choice of test organisms and various other details of the technic. Although, as the title implies, this work was done chiefly with the hydroxide, carbonate, and phosphate of sodium, the paper also report...
متن کاملCaustic skin burn caused by sodium hydroxide.
DESCRIPTION A 75-year-old, previously healthy, woman presented to the emergency room with bilateral hand wounds. Her medical history revealed the use of a sodium hydroxide (NaOH)—impregnated swab without gloves for approximately 2–3 h. Within several hours she felt a burning sensation and noticed significant hyperaemia and blisters over her left interdigitals and her right tenar eminence and fi...
متن کاملStabilization of lead in incineration fly ash by moderate thermal treatment with sodium hydroxide addition
Municipal solid waste (MSW) incineration fly ash (IFA) can be potentially reused as a substitute for some raw materials, but treatment for detoxification is indispensable owing to high contents of heavy metals in fly ash. In the present work, due to excessive leaching concentration of lead (Pb), a moderate thermal treatment with sodium hydroxide (NaOH) addition was employed to stabilize Pb in I...
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...
