Used sulfuric acid ( 98%) to lixiviate rich-manganese slags at 90-100 ℃ for 3h to dissolve out Mn, Fe, Ca, Mg etc. 作者以浓硫酸为浸取介质,在90~100℃下反应3h,将富锰渣中锰、铁、钙、镁等可溶性物质溶出,液相中的锰用来制备硫酸锰。
In this paper, the influence of adding treated chromium slag into solidified body on its compressive strength and the influence of different factors on lixiviate consistency and surface lixiviate rate of Cr ( VI) in the solid have been studied. 本文利用水泥固化水浸解毒后的铬渣,考察铬渣加入对固化体抗压强度的影响和不同影响因素对固化体中六价铬的浸出浓度、固化体表面浸出率的影响。
To make good use of used bleaching clay and increase the benefits, the recovery technology and factors of oil in used bleaching clay that produced in the process of oil bleaching were studied by use of a new-style "three-stage lixiviate reactor" that designed by ourselves. 为了更好地利用废白土增加效益,利用自行设计的一种新型三段式浸出器,对油脂脱色废白土中油脂的回收工艺及影响因素进行了研究。
Influence of Lixiviate Rate of Manganese in Rhodochrosite by Adding Addition Agent 添加剂对电解锰矿石中锰浸出率的影响
To the Paulownia, there is a little influence of lixiviate by the benzene-ethanol, as a result, the WPG was increased by 0.68%. 浸注时间影响很小。各种处理因素对泡桐树脂增重率的影响为:苯醇抽提处理不显著但有影响,经过抽提处理后,平均树脂增重率增加0.68%;
Comprehensive Utilization of Manganese Sulphate Containing Waste water from Hydroquinone Production. To Lixiviate Manganese Sulphate in Normal Temperature 对苯二酚生产中含硫酸锰废水的综合利用
The sporophore of Agaricus blazei Murrill is demolished by ultra-fine pulverization technology-a high and new industrial technology in modern food engineering, to raise the lixiviate rate of amylose. 利用现代食品工程高新技术&超微粉技术将姬松茸子实体粉碎,使其组织细胞高度破坏,提高了多糖的溶出率。
