Description

Известен способ регенерации тнтансодержаЩ6ГО сорбента путем его обработки раствором электролита.There is a method of regeneration of anthropogenic sorbent by treating it with an electrolyte solution.

Однако при таком способе процесс регенерации очень продолжителен, а дл  вытеснени  поглощенных веществ необходима предварительна  о:бработка .кислотой.However, with this method, the regeneration process is very long, and in order to displace absorbed substances, a preliminary treatment of the acid is necessary.

С целью ускорени  регенерации титансодержащего сорбента и упрощени  процесса обработку провод т смесью растворов перекиси водорода и едкого .кали.In order to accelerate the regeneration of the titanium-containing sorbent and simplify the process, the treatment is carried out with a mixture of solutions of hydrogen peroxide and caustic.

П|р.и этом отпадает необходимость предварительной обработки кислотой и резко сокращаетс  длительность регенерации.This is eliminated by the need for pre-treatment with acid, and the duration of regeneration is drastically reduced.

Пример 1. 50 мг титаногел , потер вшего обменную емкость, с содержанием ранее сорбированного никел  2,5 .мг-экв/г о.брабатывают 10 мин смесью, состо щей из 50 мл 10%1-ной Н2О2 и 50 мл 5%-ной КОН, промывают дистиллированной водой и сушат. После обра.ботки обменна  емкость составл ет 0,8 МГ-Э.КВ/Г по ионам никел  за 1 сутки при Т:Ж равном I-IOO.Example 1. 50 mg of titanogel, lost exchange capacity, with a content of previously sorbed nickel of 2.5 mg / eq / g o.b., is treated for 10 min with a mixture consisting of 50 ml of 10% 1 H2O2 and 50 ml of 5% KOH, washed with distilled water and dried. After processing, the exchange capacity is 0.8 MG-E.KV / G for nickel ions per day at T: W equal to I-IOO.

Пример 2. 50 мг титансодержащего сорбента , потер вшего обменную е.мкость, обрабатывают смесью, состо щей из 50 мл 10%-ной HaOs и 50 мл 5%-ной КОН, в течение одного часа, после чего промывают дистиллированной водой и высушивают. Потер нпа  обл1енна  емкость составл ет по иоиам меди после обработки 0,8 мг-экв/г за сутки при Т;Ж равном 1:100.Example 2. 50 mg of a titanium-containing sorbent, which lost its exchange capacity, are treated with a mixture consisting of 50 ml of 10% HaOs and 50 ml of 5% KOH for one hour, then washed with distilled water and dried. The loss of npa regional capacity is 0.8 mg eq / g per day for copper at Ioam copper after treatment at T; W is 1: 100.

В таблице пр.иведеиы данные регеиерации титансодержащнх сорбентов, отравленных никелем , по предлагаемому и известному способам .In the table pr.vedeyyy data regenieration titaniferous sorbents, poisoned by nickel, according to the proposed and known methods.

Как видио из таблицы, регенераци  по способу-прототипу требует значительно больного времени (вплоть до одних суток).As the video from the table, the regeneration according to the prototype method requires significantly more patient time (up to one day).

Предмет изобретени Subject invention

Способ регеиерацш титансодержащего сорбента путем его обработки раствором эле.ктролита , отличающийс  тем, что, с целью ускорени  возобновлени  емкости отравленного сорбента , а также упрощени  технологического процесса, в качестве электролита бе|рут смесь перекиси водорода с едким кали.The method of regenerating a titanium-containing sorbent by treating it with a solution of electrolyte, characterized in that, in order to accelerate the renewal of the capacity of the poisoned sorbent, as well as to simplify the process, a mixture of hydrogen peroxide with potassium hydroxide is used as an electrolyte.
