rate and leaching rate were investigated. The results show that sample mass loosing rate is 28.12% and iodide leaching rate is 71.56% after 900 g raw ore is roasted for 50 min at power of 16 kW......
. The method is based on the new reaction AlI3+(3/2)Zn=Al+(3/2)ZnI2. In its turn, the exchange reaction AlCl3+CaI2→AlI3+CaCl2 is used to get aluminum iodide from aluminum chloride-the product of alumina... is the chlorine, calcium iodide, and zinc recycling. Optimal temperatures for Reactions (1)-(10) are calculated with the method of total Gibbs energy minimization, used in Ref. [12]. Gas pressure 0.1 MPa......
环境水样中生化需氧量的光度法测定研究沙鸥1,顾叶华1,孙梅1,马卫兴1,郭妍2(1.江苏省连云港市淮海工学院化学工程学院环境工程系2.连云港金兆水务有限公司,江苏连云港 222005)摘 要:对传统的生化需氧量(BOD)测定方法进行了改进,采用I3--结晶紫-聚乙烯醇体系光度法测定样品培养前后的溶解氧浓度,实验以碘酸钾与过量碘化钾生成单质碘,新生成的I3-与结晶紫生成的离子缔合物在550nm处有最大吸收,采用光度法测定5天前后培养水样中溶解氧的含量来计算水样中BOD5.所拟方法用于BOD5标准样品溶液,葡萄糖-......
