Iimetali ezisindayo liqela lezinto ezilandelelanayo eziquka iimetali kunye neemetalloids ezifana ne-arsenic, i-cadmium, i-chromium, i-cobalt, i-copper, i-iron, i-lead, i-manganese, i-mercury, i-nickel, i-tin kunye ne-zinc. Ii-ion zemetali zaziwa ngokungcolisa umhlaba, umoya kunye neenkqubo zamanzi kwaye zinobuthi nokuba ziphantsi kakhulu.
Kukho imithombo emibini ephambili yeentsimbi ezinzima emanzini, imithombo yendalo kunye nemithombo yabantu. Imithombo yendalo ibandakanya umsebenzi wentaba-mlilo, ukukhukuliseka komhlaba, umsebenzi webhayoloji, kunye nokuguquka kwamatye kunye neeminerali, ngelixa imithombo yabantu ibandakanya iindawo zokulahla inkunkuma, ukutshisa amafutha, ukuhamba kwamanzi ezitalatweni, amanzi amdaka, imisebenzi yezolimo, ukumbiwa kwemigodi, kunye nokungcola kwemizi-mveliso okufana needayi zelaphu. Iintsimbi ezinzima zihlelwa njengezinobungozi kwaye zibangela umhlaza, ziyakwazi ukuqokelelana kwizicwili kwaye zibangele izifo kunye neengxaki.
Ukususwa kwee-ion zesinyithi esinzima emanzini amdaka kubalulekile ekucoceni okusingqongileyo kunye nempilo yabantu. Kukho iindlela ezahlukeneyo ezixeliweyo ezinikezelwe ekususweni kwee-ion zesinyithi esinzima kwimithombo eyahlukeneyo yamanzi amdaka. Ezi ndlela zinokwahlulwahlulwa zibe ziindlela zokufunxa, i-membrane, iikhemikhali, ii-electro, kunye nonyango olusekwe kwi-photocatalytic.
Inkampani yethu inokubonelelaIarhente yokususa isinyithi esinzima, I-Heavy Metal Remove Agent CW-15 sisixhobo sokubamba isinyithi esinzima esingenabungozi kwaye sinobuhlobo nokusingqongileyo. Le khemikhali inokwenza ikhompawundi ezinzileyo ene-ions ezininzi zesinyithi ezi-monovalent kunye ne-divalent emanzini amdaka, njenge: Fe2+, Ni2+, Pb2+, Cu2+, Ag+, Zn2+, Cd2+, Hg2+, Ti+ kunye ne Cr3+, emva koko ifikelele kwinjongo yokususa ingqondo enzima emanzini. Emva konyango, iNkunkuma ayinakunyibilikiswa yimvula, akukho ngxaki yesibini yongcoliseko.
Iingenelo zezi zilandelayo:
1. Ukhuseleko oluphezulu. Ayinatyhefu, ayinavumba libi, ayinatyhefu eveliswayo emva konyango.
2. Isiphumo esihle sokususa. Ingasetyenziswa kuluhlu olubanzi lwe-pH, ingasetyenziswa kumanzi amdaka ane-asidi okanye i-alkaline. Xa ii-ion zesinyithi zihlala kunye, zinokususwa ngaxeshanye. Xa ii-ion zesinyithi ezinzima zikwimo yetyuwa eyinkimbinkimbi (EDTA, tetramine njl.njl.) engenakususwa ngokupheleleyo ngendlela ye-hydroxide precipitate, le mveliso ingayisusa nayo. Xa inyibilikisa isinyithi esinzima, ayiyi kuthintelwa lula ziityuwa ezihlala kunye kumanzi amdaka.
3. Isiphumo esihle sokutyibilika. Ukwahlulwa kolwelo oluqinileyo lula.
4. Iintsalela zesinyithi ezinzima zizinzile, nokuba zikwi-200-250℃ okanye kwi-asidi encinci.
5. Indlela elula yokucubungula, kulula ukususa amanzi kwidaka.
Ukuba unomdla kwiimveliso zethu, wamkelekile ukubonisanaSisakunika inkonzo ngexesha loMnyhadala weNtwasahlobo.
