20110155669 | METHOD FOR TRACE PHOSPHATE REMOVAL FROM WATER USING COMPOSITE RESIN - 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. | 06-30-2011 |
20130116400 | POLYCONDENSATION OF LACTIC ACID FOR MEDICAL BIODEGRADABLE POLYLACTIC ACID CATALYZED BY CREATININE - The present invention provides a direct polycondensation method for medical biodegradable polylactic acid (PLA) using creatinine catalyzed lactic acid. The invention uses commercialized creatinine (a type of biomaterial organic guanidine compounds—the arginine metabolite creatinine (CR) in human body) as the catalyst and industrial lactic acid (LA, mass content 85-90%, aqueous solution) as the monomer to synthesize the high biosafety of medical PLA in terms of second polycondensation without solvent (identity). 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. In addition, the green catalyst and green processing method (no solvent applied and no toxic products produced) are used in the invention to synthesize the green biodegradable PLA with high biosafety. The polymerization reaction is simple and the raw materials required are low in costs, thus it is easy for industrialization. Further, the molecular weight distribution for all synthesized products is narrow and the molecular weight is controllable within 1.5-3.0×10 | 05-09-2013 |
