凯茵化工讯 澳大利亚伊迪斯考恩大学日前发表新闻公报说，该校科学家使用纳米技术制造出一种新型“金属玻璃”催化剂，可以环保、高效地处理污水。

　　“金属玻璃”又称非晶合巴斯夫水溶性金属减活剂Irgamet金，具有与玻璃类似的原子堆积结构，比晶体材料拥有更高的催化活性。

　　负责这项研究的伊迪斯考恩大学工程学院副教授张来昌在接受新华社记者书面采访中说，与目前常见的采用铁盐、铁离子等作催化剂处理工业废水的方式相比，“使用金属玻璃催化剂S先不会造成二次污染，并且其催化效率高，可重复使用超过20次。由于金属玻璃已可以大规模生产，市场价格低廉，运行维护成本也较低”。

　　张来昌的团队使用纳米技术改变了铁的原子结构，制成了原子堆积结构为“长程无序、短程有序”的新型铁基金属玻璃条。在实验室条件下，这种新型材料可以吸附染料和重金属废液中的杂质等物质，在几分钟内就可将污水净化。

　　这项研究成果近日刊登在美国《先进功能材料》科学杂志上。

　　张来昌说，已有不少国际企业，包括中国企业对这一技术表现出了兴趣，不过目前相关研究都是基于实验室模拟条件下完成的，真正大规模投入使用还需进行好终测试。“我相信此项研究会给工业污水处理带来益处。”

New "metal glass" catalyst for efficient wastewater treatment

Kailin Chemical News Australia's Edith Cowan University recently published a press release saying that its scientists use nanotechnology to create a new "metal glass" catalyst that can treat wastewater effi- ciently and efficiently.

"Metallic Glass", also known as amorphous alloy, has the atomic packing structure similar to glass and possesses higher catalytic activity than the crystalline material. In a written interview with a Xinhua News Agency reporter, Zhang Lai-chang, an associate professor of engineering at Edith Cowen University, who is in charge of the study, said that unlike the common methods used to treat industrial wastewater using iron salts and ferric ions Than, "Metallic glass catalysts do not cause secondary pollution first, and their catalytic efficiency, reusable more than 20 times. As the metal glass has been mass-produced, the market price is low, the operation and maintenance costs are also lower.

Zhang Lai-chang's team used nanotechnology to change the atomic structure of iron and made a new iron-based metallic glass strip with an atomic packing structure of "long-range disorder and short-range order." Under laboratory conditions, the new material adsorbs impurities such as dyes and heavy metal waste streams and purifies wastewater in minutes.

The research results recently published in the United States "Advanced Functional Materials" Science magazine.

Zhang Laichang said that many international companies, including Chinese enterprises, have shown their interest in this technology. However, the current research is based on the laboratory simulation conditions, and the real need for large-scale investment Conduct the final test. "I believe this research will bring benefits to industrial wastewater treatment. & rdquo;
