Sharaxaada Alaabta:
Alaabtani waa isku-dhafan kala-duwan. Waxaa loo istcimaali karaa in lagu dhex daro biraha oo waa walax xoog leh oo chelating ah oo loogu talagalay inta badan ion birta caadiga ah. Waa walax cusub oo chelating ah oo la isticmaalayey kaliya ilaa 1953. Faa'iidada ugu weyni waa awooda ay u leedahay in ay samayso saxanadaha chelates deggan ee Fe3+ ee xalalka cayriinka ah ee alkaline (pH=8-11) iyo in la sameeyo iskudhafyo deggan oo leh biro dhul dhif ah.
Codsiga:
(1) Marka lagu daro isticmaalka kiimikada falanqaynta, waxaa si tartiib tartiib ah loo isticmaalaa codsiyada kala duwan ee dunta, beeraha (cayayaanka, HEDTA-Fe ee bacriminta birta ee carrada alkaline), daawo (sida antidote ee sunta birta), maqaarka, waraaqaha, waxyaalaha la isku qurxiyo, daaweynta biyaha, electroplating, dahaadhay kiimikaad (gaar ahaan dahaadhid qalin ah), iwm.
(2) Waxay leedahay codsiyo aad muhiim u ah sifaynta iyo sifaynta toban la walaaqo.
