, lead dioxide in lead paste was reduced by glucose under hydrothermal conditions. The effects of the reaction time, glucose excess coefficient, temperature and pH on the hydrothermal reduction were systematically investigated. Under the optimized reduction conditions (i.e., temperature of 175 °C, time of 120 min, glucose excess coefficient of 3.0 and pH of 5.5), 99.9% reduction ratio of lead dioxide......

electrolytic manganese plant. Glucose and sulfuric acid were used as reductant and leaching solvent for reductive leaching of manganese anode slag. The effect of important parameters, such as temperature, sulfuric acid and glucose concentration, was investigated and the process conditions were optimized using response surface methodology (RSM) based on central composite design (CCD). The results show......
different complex agents (maltose, glucose and citric acid).XRD demonstrated that haxaaluminate is the major phase of catalyst prepared by maltose,while LaAlO3 is the major one of the catalyst by glucose and citric acid.At the same time, there is a little LaFeO3 and surface areas as well as 29.5 nm particle diameter when the complex agent is maltose.However, T10 ( temperature for 10% conversion......
_____________________________________________________________________________________________________ Abstract: Four shapes of Cu2O particles as sphere, cube, truncated octahedron and octahedron were prepared via glucose reduction of Cu(Ⅱ) under alkaline condition. The products were characterized by XRD and SEM. The effects of the precursor (CuO, Cu(OH)2), reaction temperature and glucose concentration on morphology of Cu2O particles were investigated, and the mechanism of morphology......
parameters,such as particle size,glucose percentage in the culture medium,bioleaching time,and solid/liquid ratio were optimized.Optimum bioleaching conditions were found as follows:particle size of 150-177 μm,glucose percentage of 6%,bioleaching time of 8 d,and solid/liquid ratio of 1:80.Under these conditions,53% of copper was extracted.关键词:......
