Tikanga Whakahāngaitanga Glyoxal o te Waikawa Oxalic
He kaha te whakaitiiti o te Glyoxal, nō reira ka taea te tere te whakapūkara ki te waikawa oxalic i raro i te mahi a te waikawa hauota whakapūkara kaha. Nā ngā āhuatanga pēnei i te tuku rauemi mata, te utu, me te hangarau, he iti te whakataetae mākete o tēnei tikanga, ā, kāore anō kia whakawhanakehia kia ahumahi.
Hei tāpiri, kei reira ētahi atu tikanga hanga mō te waikawa oxalic:
(1) Tikanga whakarite hauhā waro: Ka whakaitihia tuatahitia te hauhā waro ki te takawaenga
CO2
kātahi ka hurihia hei matū rauropi kē atu. Ka whiwhihia te waikawa oxalic mā te whakamātao i ngā pūnaha hauhā waro maha mā roto i ngā tikanga hikohiko me ngā hihi-γ, te rā, ngā rama mercury pēhanga teitei rānei.
(2) Te tikanga whakarewa kawakawa mā te whakamahi i ngā rauemi whai kiko-cellulose: Ka whakarewahia ngātahitia he ranunga o ngā rauemi whai kiko-cellulose (pēnei i te rakau para, te papapa, me ētahi atu) me te kawakawa kaha kore-organika ki te 513–558 K hei whakaputa i te neke atu i te 50% oxalate. Ka whakapūpūtia ngā tioata oxalate mā te whakapūpūtanga, kātahi ka whakamahia te waikawa whanariki hei whiwhi i te waikawa oxalic kua oti. He māmā noa te tukanga o tēnei tikanga mō te whakarite waikawa oxalic, engari he iti te tere tahuritanga kotahi-haerenga (iti iho i te 35%), he nui te kai kawakawa, ā, he kino te parahanga taiao.
(3) Tikanga whakaputa rauemi mata waro: I hangaia mai i ngā momo peat hei rauemi mata. Hei tauira, ka hangaia te waikawa oxalic mai i te peat o te momo Sphagnum me Polytrichum mā te whakakōkī waikawa hauota. Ka mahia te tauhohenga i te 343 K mō ngā haora 8–9, me te hua tae atu ki te 95%. Ina whakamahia ngā rauemi mata pēnei i te tāra waro hei whakaputa waikawa oxalic, ka eke hoki te hua ki te 51%.
