摘　　要：磷酸吡哆醛是一种水溶性维生素,对人体内氨基酸反应有着促进作用,可作为治疗多种疾病的药物在医药方面的应用广泛,该物质合成时多以盐酸吡哆醇(VB6)为起始原料,经二氧化锰氧化反应、醛基保护、磷酸酯化和水解反应合成磷酸吡哆醛。本文利用吡哆醛生产过程中产生的含锰废水,采用分阶段调控耦合膜过滤技术处理,利用化学沉淀与膜过滤法相结合协同处理,资源化利用制备碳酸锰。Pyridoxal phosphate is a kind of water-soluble vitamin, which can promote the amino acid reaction in human body. It can be widely used as a drug to treat many diseases. Pyridoxal phosphate was synthesized from pyridoxine hydrochloride(VB6) by MnO2 oxidation, aldehyde protection,phosphate esterification and hydrolysis. In this paper, the manganese-bearing wastewater from pyridoxal production is studied. The manganese-bearing wastewater is treated by the coupling membrane filtration technology of regulation and control in stages, preparation of manganese carbonate by resource utilization.
