| 摘 要： | 以Al2O3为载体制备了负载型催化剂,通过甲酸催化还原脱除地下水中硝酸盐对该催化剂进行了活性评价,并研究了催化剂制备条件对催化性能的影响,发现催化剂种类、配比及其含量不同,催化剂的催化性能也相应发生变化,其中4%Pd-1%Cu/Al2O3催化剂可以在45min内将100mg/L的NO3-被完全去除。

| Abstract: | Different kinds of catalyst:including monometallic and bimetallic with Pd and Pd-Cu supported over Al2O3 were prepared,and the performances for reducing nitrate in groundwater investigated.It has been found that nitrate removal depends on kind of catalyst,ratio of Pd/Cu and metal loading,duration of catalytic reaction affects nitrate removal as well. |
