Whakamahinga
Ngā whakamahinga matua o te phenolphthalein: 1. Te umanga rongoā hei rauemi mata mō te rongoā: He pai mō te mate puku auau me te puku uaua, ā, e wātea ana i roto i ngā momo horopeta pērā i ngā papa me ngā suppositories. 2. Mō te hanga rauropi: Ka whakamahia whānuitia mō te hanga kirihou, inā koa mō te hanga i ngā polymers diazazone polyaryletherketone. He tino pai te ātete wera o ēnei polymers, te ātete wai, te ātete waikura matū, te ātete koroheketanga wera, me te pai o te tukatuka me te hanga. Kāore i roa ka whakamahia whānuitia ngā muka, ngā paninga me ngā rauemi hiato i hangaia mai i a ia i roto i ngā mara pērā i te hikohiko me ngā taputapu hiko, ngā taputapu mīhini, te kawe waka, te rererangi, te miihini pūngao atomika me te ope taua. 3. Ka whakamahia hei tohu waikawa-pūtake, hei tohu mō te titration otinga kore-wai, me te matū mō te tātari chromatography.
He hua tēnei e whakamahia whānuitia ana hei rongoā mō te waikawa, ā, ko te awhe hurihanga tae he pH 8.2 (kore tae) -10.0 (whero). He momo rongoā anō hoki te Phenolphthalein. Hei rongoā whakawai, ka mahi ki te koroni, ā, ka whakamahia hei rongoā i te mate puku.
E whakamahia ana hei tohu waikawa-pūtake me te rongoā whakangāwari i te puku hei rongoā i te mate pāwera
Ngā tohu waikawa-pūtake, ngā tohu ine ira wai kore-wai, ngā tauhohenga tātari chromatography.
