The color of dye aqueous solution which cannot be removed by coagulation was selected to decolourize it through adsorption process using novel adsorbents namely Flocs Ferric Sulphate, Aluminium sulphate and Manganese sulphate. In order know efficacy adsorbents, batch sorption studies equilibrium were conducted. Good removal achieved with at pH::4 Sulphate pH::10, will applicable reduce the indu...

BACKGROUND Dentin surface contaminated with haemostatic agents can interfere with the bonding of self-adhesive resin cement. Therefore the purpose of this study was to evaluate the effect of various haemostatic agents such as Aluminium chloride, Ferric sulphate and Tannic acid on the shear bond strength of self-adhesive resin luting agent. MATERIAL AND METHODS The buccal surfaces of extracted...

PURPOSE The purpose of this study was to test the hypothesis that the pulp medication ferric sulphate (FS) may remain on primary dentin, affecting its microchemical structure and the bond strength of adhesives to primary dentin. MATERIALS AND METHODS The effects of FS and pre-bonding conditioning (37% phosphoric acid [PA] for 15 s or a self-etching primer, with or without the use of 2% chlorh...

The use of potassium ferrate(VI) as an alternative water treatment chemical for both drinking water and sewage treatment has been studied and is reported in this paper. The performance of potassium ferrate(VI) was evaluated in comparison with sodium hypochlorite (NaOCl) and NaOCl plus ferric sulphate (FS) and aluminium sulphate (AS). The effects of the dosages of ferrate(VI), NaOCl and FS/AS an...
