    摘要: A deep purification method for removing trace thallium in water by using polymer-based nanosized manganese oxide is disclosed. This method comprising the following steps: adjusting the pH value of the water polluted with trace thallium to 5-8.5 and filtering it, then channeling the water so treated through a packed tower of filtering bed packed with polymer-based nanosized manganese oxide so that the thallium in water can be selectively adsorbed upon the nanocomposite material, stopping the adsorption process when the thallium in water reaches the leak point, and then using mixed solution of HCl—Ca(NO3)2 or NaOH—NaClO as the desorption agent and starting desorption and regeneration process for the packing material of polymer-based nanosized manganese oxide. This effectively reduces the concentration of thallium in water from 0.01-0.5 mg/L to lower than 0.1 μg/L, despite the much higher concentration of coexisting competitive cations such as Ca2+, Mg2+, Na+ and Si(IV).

    摘要: The invention discloses a novel method for trace phosphate removal from water by using a composite resin. Firstly, adjusting the pH value of the raw water to 5.0˜9.0 and prefiltering the water, then leading the filtrate through an absorption tower packed with the composite resin, the trace phosphate in the water is therefore absorbed onto the composite resin; stopping the absorption run when it reaches the leakage point, using a binary NaOH-NaCl solution as the regenerant of the exhausted sorbent, followed by rinsing the composite resin-filled absorption tower with saturated carbon dioxide solution to regenerate the resin. In this invention, a composite resin with nanosized hydrated ferric oxide (HFO) or hydrous manganese dioxide (HMO) particles loaded on its surface is adopted as the absorbent for enhanced phosphate removal from water. A significant decrease of phosphate content in the effluent from this treatment system is found from 0.05-20 ppm to less than 20 ppb (calculated in P), despite of the coexisting competing anions as sulfate, chloride, and hydrocarbonate at much higher molar concentrations than phosphate. This invention is characteristic of large treatment capacity and efficient regeneration for repeated use of the absorbent.

    摘要: A direct polycondensation method for medical biodegradable polylactic acid (PLA). The invention uses commercialized creatinine (a type of biomaterial organic guanidine compounds—the arginine metabolite creatinine in human body) as the catalyst and industrial lactic acid (mass content 85-90%, aqueous solution) as the monomer to synthesize the PLA in terms of second polycondensation without solvent. Instead of tin catalysts having cytotoxicity, the catalyst used in the invention has high biocompatibility and biosafety. The synthesized PLA does not contain any metal and other toxic components; therefore, it can be used as the carrier for targeting drugs and controlled release drugs. The green catalyst and green processing method (no solvent applied and no toxic products produced) are used to synthesize the green biodegradable PLA with high biosafety. The molecular weight distribution for all synthesized products is narrow and the molecular weight is controllable within 1.5-3.0×104.
