  1. Some main results of testing research were as fellows : i. in the course of testing of leaching zinc dross, leaching zinc dross by sulfuric acid was researched and the effects on the leaching rate of the zinc dross were analyzed by author, the optimum conditions of leaching testing of zinc dross were determined as fellows : liquid - solid ratio 6 : 1, stirring ratio 250r / min, granularity 120 mesh, the soaking time 5h, the concentration of sulfuric acid of 30 %, and under these conditions, the rate of leaching zinc is above 92. 0 %. ii. in the course of testing of purification, on the basis of comprehending and comparing all present methods of the manganese - removal and iron - removal, the oxidizing method of manganese - removal in zinc sulfate solution using ammonium persulfate was put forward and the oxidizing method of iron - removal in zinc sulfate solution using the goethite process and oxidation - hydrolysis process was adopted

    研究的主要結果具體如下: 1 、研究了硫酸浸出鋅浮渣並分析了影響浸出率的各種因素,確定了浸出鋅浮渣的最佳條件為:液固比為6 : 1 ,攪拌速度為250r min ,粒度為- 120目,酸浸時間為5 . 0h ,硫酸濃度30 ,鋅浮渣的浸出率大於92 . 0 ; 2 、在綜合和比較了目前除錳和除鐵的各種方法基礎上,提出了過硫酸銨氧化除錳方法和選擇了針鐵礦-氧化水解聯合法除鐵方法,並分析和討論了影響除錳率和除鐵率等各種因素,確定了除錳的條件為:溫度90 , ph值5 . 4 ,反應時間3h ,過硫酸銨達到理論值的1 . 2倍,除錳率超過99 . 86 ;聯合法除鐵的條件為:氧化反應時間1 . 5小時、溫度控制在90 92 、 ph值5 . 2 5
  2. Surface roughness of coatings affects the bioacitivity of materials, in order to change the roughness of coatings, the granularity of coating powders was changed firstly. nanometeral anatase titanium dioxide powders were prepared by hydrolysis of titanium - tetrabutoxide with ethanol in this paper. the main particle size is between 5nm and 10nm, while the size of ordinary titanium dioxide powders is about 100nm

    為了改變塗層表面的粗糙度,實驗中從改變塗層粉末的粒度入手,以鈦酸丁酯為原料,通過醇鹽水解法制備了納米級銳鈦礦型tio _ 2超細粉,粒徑約為5 10nm ,而普通二氧化鈦粉體的粒徑多在100nm左右。
