Tikanga Whakapūtā Konutai o te Waikawa Oxalic
Ko te hanga waikawa oxalic mā te tikanga konutai formate e wehea ana ki te tikanga mata me te tikanga konupūmā. Ka mimitihia te hauota waro e te wairewa konutai hauwai hei whiwhi i te konutai formate, kātahi ka tangohia te hauwai hei hanga i te konutai oxalate. Ka tauhohe te mea whakamutunga ki te whanariki mata (tikanga mata) te konupūmā hauwai rānei (tikanga konupūmā) hei hanga i te mata oxalate mata, i te konupūmā oxalate rānei, kātahi ka whakawaikawahia ki te waikawa whanariki hei whiwhi i te waikawa oxalic.
Tikanga arataki mō te hanga waikawa oxalic: Whai muri i te horoinga, te horoi kawakawa, me te tango puehu, ka pēhia te hauota waro ki te 2 MPa e te pūwero, ka whakamahanahia ki te 150 °C me te 160 g/L konutai hauwai, ka tukuna ki te tauhohenga hei hanga i te otinga konutai formate memeha. Ka whakatōkia te otinga ki te 600 g/L, ka tukuna ki te ipu waikura hei whakamahana, hei whakatōkia hei totoka, kātahi ka whakamahanahia, ka rewa, ka waikura ki te 400 °C. Ka whakaritea te konutai oxalate waikura hei whakatārewatanga, ka tāpirihia te konutai arataki me te whakaoho tonu i te uara pH ki te 3–4. Ka tangohia ngā poke wairewa mā te horoi, kātahi ka tāpirihia te waikawa whanariki nui hei whakakawa hei whiwhi i te otinga waikawa oxalic. Ka tāpirihia te barium carbonate me te 1% polyacrylamide hei whakapūmau me te whakatō hei tango i ngā poke. Ka whakamataohia te otinga, ka whakatio, ka tātarihia mā te centrifugation, ka whakamarokehia kia whiwhi ai i te hua kua oti.
Tikanga konupūmā mō te hanga waikawa oxalic: Ka inehia te whakatārewatanga konutai oxalate me te whakatārewatanga konupūmā hauwai kua oti te whakarite, ka tukuna ki te tauhohenga konupūmā mō te tauhohenga konupūmā i raro i te whakaoho. Ka tātarihia, ka horoia te wai konupūmā i whiwhihia. Ka whakawhāitihia te tātari konutai hauwai ka whakamahia hei hanga konutai formate, ā, ka whakamahia te keke tātari konupūmā oxalate mō te tauhohenga waikawa. Ka whakaritea te keke tātari hei whakatārewatanga konupūmā oxalate, ka whakawaikawahia ki roto i te ipu whakawaikawa me te waikawa whanariki me te wai whaea waikawa oxalic kukū, kātahi ka tātarihia. Ka horoia te keke tātari (gypsum), ā, ka whakamahia te wai horoi hei whakarite i te whakatārewatanga konupūmā oxalate. Ka mimitihia te tātari (te otinga waikawa oxalic) hei tango i ngā matūriki konupūmā whanariki pai, ka whakamataohia, ka whakatiotia, ka whakapokapūhia hei wehe i te waikawa oxalic mata, ka whakatiotia anō, ka wehea, ka whakamarokehia kia whiwhi ai i te hua tika, ā, ka hangarua te wai whaea.
He tukanga pakari te tikanga mata konutai formate, he kounga hua pumau, ā, he poto te huringa whakaputa, me te hua o te 80%–90% me te parakore o te waikawa oxalic kua whakatikatikaina o te 99.5%. Heoi, kei roto i te tukanga whakaputa te parahanga mata, ā, kāore e taea te whakahoki i te konutai whanariki i puta mai i te tauhohenga ki te tukanga, nō reira he nui te waikawa whanariki me te houra tunutunu e pau ana i te whakaputanga. Mā te tikanga konupūmā mō te hanga waikawa oxalic ka taea te whakakore i te parahanga o ngā tote mata me te konutai whanariki ki te wai whenua, ā, mā te whakakapi i te houra tunutunu ki te raima ka taea te whakaiti i ngā utu whakaputa. Ka taea te tukatuka i te hua taha CaSO4 i puta mai i te tauhohenga hei rauemi hanga me te kore e parahanga. I taua wā anō, ka whakamahia te wai whaea NaOH i puta mai i te tauhohenga ki te tauhohenga ki te CO hei whakarite i te konutai formate, ā, ka penapenahia te nui o ngā rauemi mata.
