OBJECTIVE To enhance the dissolution rate of daidzein with solid dispersion technique. METHOD Solid dispersions were prepared by the solvent method using water-solubility chitosan as a hydrophilic carrier. DSC, IR and X-ray methods were used to verify the formation of solid dispersion. RESULT Dissolution percentages of solid dispersions were more than(More)
To improve the recovery of copper, the viscosity of copper molten slag is decreased by the reduction of magnetic iron, which, in turn, accelerates the settling and separation of copper droplets from the slag. A new technology is proposed in which waste cooking oil is used as a reductant to reduce magnetic iron in the copper smelting slag and consequently(More)
