【摘要】 以工业级碱式碳酸锌为原料应用直接沉淀法制备纳米ZnO粉体,同时采用了自然集菌法和抑菌圈法对其抗菌性能进行了研究。研究表明:此法可制得粒径较小的纳米ZnO,其操作简便易行,对设备、技术要求不高,不易引入杂质,成本低,易于工业化生产;且制备的纳米ZnO具有较强的抗菌性能。更多还原

【Abstract】 The test used basic ZnCO₃ in industry level as raw materials, nanometer sized ZnO was prepared by direct precipitation method, at the same time, it puts up research to determine their antibacterial capability with two methods∶nature bacterium collection and bacterium repress in circle.The results showed that the it can gain nano-ZnO of smaller granule, its operation simple, its request not high equipment and technique, not easy induct impurity, its cost low,and industry production is easy; in addition, the nano-ZnO will possess stronger antibacterial capability.更多还原
