According to the results, vermi- compost leach liquor reduced average grain number by 2.1%, significantly increased 1 000-grain weight by 15.2%, enhanced grain weight and grain yield by 6.4% and 4.3%, improved grain starch content, protein content and wet gluten content by 1.5%, 1.4% and 2.3%, respectively, and declined moisture content by 12.3%. Apply- ing vermicompost leach liquor after blooming stage is an effective method to im- prove varietal characteristics, grain weight, yield and quality of wheat.展开更多

The separation of rhenium from the electro-oxidation leachate of molybdenite and its mechanism were investigated. The results show that pH of the leachate significantly affects adsorption rate compared with other experimental parameters. When temperature is 30℃, pH=8, and adsorbing time is 1 h, adsorption rates of rhenium and molybdenum are 93.46% and 3.57%, respectively, and separation factor of D301 resin for rhenium and molybdenum is 169.56. In addition, the separation factor is higher when the initial molybdenum concentration in model solution is increased. The saturated adsorption capacity of D301 resin for molybdenum and rhenium calculated based on simulated results are 4.263 3 mmol/g and 4.235 5 mmol/g, respectively. D301 resin is an effective separation material of rhenium from electric-oxidation leachate of molybdenite. The adsorption kinetics results also show that the adsorption of rhenium is easier than that of molybdenum, and the adsorption process of D301 for rhenium and molybdenum may be controlled by liquid film diffusion.展开更多
