| 摘 要： | 以工业锰浸出渣制备白炭黑和锰肥,对制备的白炭黑进行了详细表征,白炭黑为纳米孔道结构,其比表面积达到198m2/g、孔体积为0.45ml/g、平均孔径为9.10nm、BJH孔径为6.54nm。提取白炭黑之后的废渣中水溶性锰的含量为1.6%、枸溶性锰含量为5.1%,均达到锰肥对水溶性锰和枸溶性锰含量的要求,可以制备锰肥,并探讨了防结块剂的用量对锰肥结块时间的影响,获得较好的锰肥配方工艺。

| Abstract: | Silica white and manganese fertilizer were prepared by the main material of the industrial manganese slag in this paper.Silica white with nanopore structure obtained was characterized in detail,and its specific surface area,pore volume,average pore diameter and BJH pore diameter were 198m2/g,0.45ml/g,9.10nm and 6.54nm respectively.Water-soluble manganese and citrate soluble manganese content of the slag after preparing silica white were 1.6%and 5.1%,which reached the requirement of the contents of water-soluble and citrate soluble manganese fertilizer.Therefore,the slag could be used to produce manganese fertilizer.Meanwhile,the influence of anti-caking dosage on caking time of manganese fertilizer was explored.The satisfactory manganese fertilizer formula was obtained. |
