Ibyuma bikomeye ni itsinda ry'ibintu bifatika birimo ibyuma na metalloids nka arsenic, cadmium, chromium, cobalt, copper, iron, lead, manganese, mercure, nickel, tin na zinc. Ion z'ibyuma zizwiho kwanduza ubutaka, ikirere n'amazi kandi ni uburozi nubwo haba hari ingano nkeya cyane.
Hari amasoko abiri y'ingenzi y'ibyuma biremereye mu mazi, amasoko karemano n'amasoko akomoka ku bantu. Inkomoko karemano irimo ibikorwa by'ibirunga, isuri y'ubutaka, ibikorwa by'ibinyabuzima, no kuzura amabuye n'amabuye y'agaciro, mu gihe amasoko akomoka ku bantu arimo aho imyanda ijugunywa, gutwika ibicanwa, amazi asohoka mu mihanda, imyanda y'amazi mabi, ibikorwa by'ubuhinzi, ubucukuzi bw'amabuye y'agaciro, n'imyanda ihumanya nk'irangi ry'imyenda. Ibyuma biremereye bishyirwa mu byiciro by'uburozi n'ibitera kanseri, bishobora kwirundanya mu ngingo bigatera indwara n'ibibazo.
Gukuraho iyoni z'icyuma gikaze mu mazi yanduye ni ingenzi mu gusukura ibidukikije n'ubuzima bw'abantu. Hari uburyo butandukanye bwatangajwe bwo gukuraho iyoni z'icyuma gikaze mu mazi yanduye atandukanye. Ubu buryo bushobora gushyirwa mu byiciro bibiri: uburyo bwo kuvura bushingiye ku gukurura, gukoresha membrane, chemical, electrocatalytic na photocatalytic.
Isosiyete yacu ishobora gutangaUmukozi Ukuraho Ibyuma Biremereye, Heavy Metal Remove Agent CW-15 ni umuti ufata ibyuma bikomeye udahumanya kandi ntubangamira ibidukikije. Uyu muti ushobora gukora ikintu gihamye gifite monovalent na divalent ions nyinshi mu mazi yanduye, nka: Fe2+, Ni2+, Pb2+, Cu2+, Ag+, Zn2+, Cd2+, Hg2+, Ti+ na Cr3+, hanyuma ukagera ku ntego yo gukura mu mazi ibintu bikomeye. Nyuma yo kuvurwa, imvura ntishobora gushonga kubera imvura, nta kibazo cy’umwanda cya kabiri kibaho.
Ibyiza ni ibi bikurikira:
1. Umutekano mwinshi. Nta burozi, nta mpumuro mbi, nta bintu by'uburozi byakozwe nyuma yo kuvurwa.
2. Ingaruka nziza zo gukuraho. Ishobora gukoreshwa mu rugero rwa pH runini, ishobora gukoreshwa mu mazi yanduye aside cyangwa alkaline. Iyo iyoni z'icyuma zifatanye, zishobora gukurwaho icyarimwe. Iyo iyoni z'icyuma ziremereye ziri mu buryo bw'umunyu ugoye (EDTA, tetramine n'ibindi) udashobora gukurwaho burundu hakoreshejwe uburyo bwa hydroxide precipitate, iki gicuruzwa gishobora no kugikuraho. Iyo gishongesheje icyuma kiremereye, ntikizabangikanywa byoroshye n'umunyu ufatanye mu mazi yanduye.
3. Ingaruka nziza zo gukurura amazi. Gutandukanya amazi akomeye n'amazi byoroshye.
4. Ibisigazwa by'icyuma biremereye birahamye, ndetse no ku bushyuhe bwa 200-250℃ cyangwa aside ivanze.
5. Uburyo bworoshye bwo gutunganya, bworoshye gukuramo amazi mu myanda.
Niba ushishikajwe n'ibicuruzwa byacu, Murakaza neza kugira ngo mugire inamaTuracyagukorera mu gihe cy'Iserukiramuco ry'Impeshyi.
