Barren mountain greening technology

The invention belongs to the technical field of barren mountain greening ecological protection, relates to a rock vegetation establishment and construction technology for barren mountain rock greening and preventing water loss and soil erosion, particularly to preparation and construction process of a barren mountain rock greening material. In the early stage, the barren mountain rock greening material is a liquid-solid mixture and comprises adhesives, organic soil, foam materials, plant seeds and the like. The barren mountain rock greening material is placed on barren mountain rocks or the outer wall of a building through spray-seeding, capable of foaming at normal temperature, and finally formed into an adhesive layer, an organic soil layer, a porous foam framework for fixing the organic soil layer and plant seeds and a phytocoenosium layer. The barren mountain rock greening material is pollution-free and capable of achieving natural degradation in a certain period of time. According to the barren mountain greening technology, establishment and construction can be successfully achieved through one-time spray-seeding, the construction technology is simple, later manual maintenance is not required, and the material is environment-friendly, can be firmly adhered to rocks or the surface of the building, resist rain impact, hold moisture, retain fertilizer and be high in air permeability.

Preparation method of molybdenum separation resin

The invention relates to a preparation method of molybdenum separation resin. The preparation method comprises the following steps of: (1) preparing a dispersing agent solution; (2) preparing an alpha-benzoinoxime contained organic phase; (3) preparing a styrene-divinylbenzene prepolymer; and (4) synthesizing the resin: adding the styrene-divinylbenzene prepolymer into the dispersing agent solution, stirring the mixture so that the styrene-divinylbenzene prepolymer is dispersed into bead bodiese, and slowly heating to 65-70 DEG C; adding the alpha-benzoinoxime contained organic phase, continuing to heat to 80-85 DEG C, reacting for 10-15h, stopping heating and naturally cooling the alpha-benzoinoxime contained organic phase; and when the temperature is reduced to 40-50 DEG C, filtering a reaction mixture, cleaning a sediment and naturally airing the sediment. The molybdenum separation resin obtained by using the method provided by the invention is stable in structure, firmness of an extraction color layer is good when the molybdenum separation resin is used for molybdenum extraction, and the selectivity of the alpha-benzoinoxime to molybdenum is greatly improved; and experiments and tests prove that the molybdenum separation resin provided by the invention has the saturation adsorption capacity as follows: 36-43mg of molybdenum is contained in each gram of dry resin.
