[求助] 12钨锌酸合成求助~翻译~

The mother-liquors were extracted with ether and 12N-sulphuric acid. The ether addition compound formed was purified by dropping it through several portions of ether. On dilution with water, the ether separated and was removed by evaporation. The aqueous solution was evaporated to dryness on a steam-bath and the tungstic acid, formed by the decomposition of the metatungstic acid present, removed by filtration. The process was repeated until little tungstic acid was precipitated. The final aqueous extract was concentrated to small bulk, first on the steam-bath and then over concentrated sulphuric acid in a partial vacuum.

本小硕最近在合成锌钨十二，前期步骤已经合成完毕，但是对过滤液的后续处理不是很明白啊，以上是我要进行的步骤，是说用乙醚萃取以后蒸汽浴浓缩，然后把液体再次浓缩以后在浓硫酸下干燥吗？求各位大神帮帮忙啊啊，感激不尽~~
