Whakaahuatanga Hua:
Ko tenei hua he whakauru maha. Ka taea te whakamahi ki te whakauru i nga konganuku, me te mea he kaihoko chelating kaha mo te nuinga o nga katote whakarewa noa. He kaihoko chelating hou kua whakamahia noa mai i te tau 1953. Ko te tino painga ko tona kaha ki te hanga i nga kopae chelate pumau me te Fe3+ i roto i nga wairewa mata kawakore (pH=8-11) me te hanga i nga whakauru pumau me nga konganuku whenua onge.
Taupānga:
(1) I tua atu i tona whakamahinga i roto i te matū tātari, kei te whakamahia haeretia i roto i nga momo tono mo te kakano, ahuwhenua (pesticides, HEDTA-Fe mo te whakakikiritanga rino i roto i nga oneone kawakore), rongoa (hei rongoa mo te paihana rino), hiako, pepa, poke, maimoatanga wai, electroplating, matū whakakikorua (ina koa i roto i te whakakikorua hiriwa), etc.
(2) He tono tino nui i roto i te para me te purenga o te dilute tekau.
