摘要
本文采用微波消解—自动电位滴定法测定铁矿石全铁量。重点研究自动电位滴定仪编写空白的滴定程序编写的方式对结果的影响、设计滴定程序,以经典的手工滴定法作对比,结果相似,达到滴定过程的自动化。结果表明:本法适用于铁矿石中全铁量的检测,测定范围为40%～70%,相对标准偏差小于2%。
A method based on Time Slice Model （TSM） is proposed for batch processes heat exchanger network synthesis by taking place. Total iron content in iron ore was determined by automatic potentiometric titrator and the sample was digested by microwave. The program designing for blank was discussed which effect on the results, and also the program designing for total titration, and then the results conformed to the manual titration method. The method applies to determination of total iron content in iron ore, the inspection range was 40%-70%, RSD 〈2%.
