Abstract: A method is disclosed for removing Se(IV) from aqueous solutions. The method begins by oxidizing an aqueous selenium solution with an aqueous oxidant to produce a Se(IV) solution. The Se(IV) solution is then contacted with a solid sorbent. The Se(IV) from the Se(IV) solution is then simultaneously adsorbed and encapsulated onto the solid sorbent to form an exhausted sorbent. The exhausted solid sorbent can then be disposed.

Abstract translation: 公开了一种从水溶液中除去Se（IV）的方法。 该方法通过用含水氧化剂氧化硒水溶液开始生成Se（IV）溶液开始。 Se（IV）溶液然后与固体吸附剂接触。 然后将来自Se（IV）溶液的Se（IV）同时吸附并封装在固体吸附剂上以形成吸尽的吸附剂。 然后可以处理用尽的固体吸附剂。
