Early removal of the aspirated tablet prevents acute complications such as bronchial necrosis hemoptysis and lobar consolidation Tablet removal is also necessary to prevent late bronchial stenosis We presented the first case in Korea of a ferrous sulfate tablet aspiration that induced severe endobronchial inflammationGet Price
Lead or cadmium removal as affected by essential metals Selective removal of lead or cadmium by PGASPIONs in the presence of several biologically important essential metals was studied in a bisolute system by incorporating potassium calcium magnesium zinc iron or copper into the metal solution at a ratio of 11 leadcadmiumessentialGet Price
Ferric Sulfate Properties The molecular formula for this chemical is Fe 2 SO 4 3 and its molecular weight is 399858 gmol It is slightly soluble in water sparingly soluble in alcohol and has negligible solubility in acetone and ethyl is insoluble in sulfuric acid and ammonia Ferric sulfate is produced on a large scale through the reaction of sulfuric acid an oxidizing agentGet Price
Jul 01 2000 · Fig 3 Fig 4 show the effects of the dosage of hydrogen peroxide and ferrous sulfate on the COD removal efficiency Both the overall COD removal efficiency and the efficiency by oxidation in Fig 3 were increased by increasing the dosage of hydrogen peroxide As it appeared in the intercept of the yaxis of Fig 4 in which hydrogen peroxide was not added the removed COD value by oxidationGet Price
Surface finishing of steel sheets and strips for the removal of iron oxide scale generates a huge amount of waste sulfatechloride pickle liquor Similarly large quantity of bleed stream is generated in the electrolysis industries due to the build up of acidity and metal impurity The nature of the waste generated has become complex and hazardous in nature Their impacts on ecological bodiesGet Price
