摘要
介绍了利用铁粉还原实验废液中的单质I_2和在碱性条件下,用H_2O_2还原KIO_3制得KI.该方法操作简便,易分离、提纯,产率高。
It is reported that KI is recovered from the waste solutions in chemical experiments by reducing I_2 with iron powder and reducing KIO_3 with H_2O_2 under the alkaline condition.The methods simple,convenient and easy to separate and purify.
