Hydrogen peroxide
Neno wi piny ma jucul
Nying kemikol: Hydrogen Peroxide
Namba pa CAS: 7722-84-1
Formula pa molecule: H₂O₂
Pek pa piny: 34.01 g/mol
Kite ma nen kudu: Piny ma rangi epe, maleng, ma nguc ungo (ma nok) nituc i pii ma nyap nyanok (ma lee)
Piny ma pol: 3% (i ot/mi yath), 30% (i tic), 50-70% (i tic ma leng)
Hydrogen peroxide (H₂O₂) ubedo piny ma tek man ma tiyo ku yore madwong ma julwongo pi kero pare mi nyai i pii (H₂O) man oxygen (O₂) — ma weko ngo piny moko marac. Kite ma ber pa kwo pa piny, man ku tego pare mi nyayu yamo, weko ebedo piny ma pire tek i ot, i ot yath, i tic mi yubu piny, man i tic mi fur. Etiye i rwom ma juyiko pi rombu ku yeny moko, nicaku i gwoko ret ma yot nitundu i tic ma tek mi tic.

H₂O₂'s adaptability miyo ebedo piny ma pire tek ikind tic matung tung, ku ketho cwiny ikum tic:
3.1 Yath man yot kum (3-6% Concentrations)
Yath pa ret: Yath ma 3% jutiyo kudu lee pi lwoko ret ma nok, ret, man wang — ma nyayu oxidizing pathogens man eketho piny ma gwoko kum ikum two.
Leng pa lak: Jumedo i yath mi lwoko lak pi jwigu plaque, neko bacteria ma nyayu yuyu marac, man dwoko lak tar (i yore ma jugwoko maber).
Gwoko jam tic mi yath: Yath ma nok nyayu two i jam tic ma nyayu two ngo (calu, thermometers, jam tic mi lak) manangu nyayu ngo peko i kum piny.
3.2 Piny mi ot man piny ma dhanu tiyo kudu (3-10% Concentrations)
Laundry Bleaching: Yore maber pa chlorine bleach; dwoko bongo ma tar (pamba, linen) man wodhu rangi macol (kawa, chai, rimo) manangu rangi migi rwinyo ngo.
Lwoko piny: Eketho kwidi iwi mesa mi jokoni, piny mi ot lwok, man wi ot — maber ikum lum, lum, man kwidi ma wok kud i cam (e.g. E. coli, Salmonella).
Gwoko yuk wic: Jutiyo kudu i yore mi yiko yuk wic (6-10% concentration) mi dwoko yuk wic ler ni kadhu kud i oxidizing melanin.
3.3 Tic mi yubu piny (30-70% Concentrations)
Paper & Pulp Bleaching: Tic madit uloyu i tic — 30-50% H2O2 dwoko ler pa yen pi karatasi maber (calu, tissue, karatasi mi goyo) manangu epe ku piny ma rac pa chlorine.
Yubu bongo: Weko bongo macol (pamba, yuk yuk) man bongo ma juyubu (polyester) ma leng; dwoko ler pa bongo man rangi pare bedo maber ma podi jupoko ngo rangi.
Yubu pii ma cido: Turo piny ma rac (phenols, dyes, cyanides) man dwoko piny COD/BOD; wodhu oxygen pi medo tic pa bacteria ma timo tic ku yamo.

Pirango ma wayero Hydrogen Peroxide mwa?
Jam piny ma juyike: Wabe miyo 3% (mi yath/mi ot), 30% (mi tic), man 50-70% (ma leng) pi rombu ku yeny peri.
Ultra-Pure Formulations: Low heavy metal man impurity levels miyo bedo ber ku piny ma pire tek (e.g., jam tic, yath).
Jam piny ma rwinyo: Kabedo mwa mi yubu piny (ma romo oro acel: 100,000 tons) mio genogen mi kelo piny i sawa ma mitire pi piny madwong man ma nok.
Eco-Friendly: Eloko doko pii man oxygen — konyo yub mi kwo maber (e.g., loko kemikol ma tiye ku chlorine).
Kony mi tic: Udul mwa mi chemistry miyo telowic ikum dilution, gwoko, man tic maber.
