Isicelo

I-Alpha Nephthophyllein isetyenziswa njengesalathisi se-asidi. Ayinabala ukuya kumthubi orenji kwipH emalunga ne-6.7 kwaye iyatshintsha ukusuka kumthubi o-orenji ukuya kubhlowu ngepH emalunga ne-7.9. Ukungcola kwiimveliso ezithengiswayo zihlala zibonakala njengombala obomvu okhanyayo, oguqukayo ukusuka ekukhanyeni obomvu ukuya eluhlaza okwesibhakabhaka kwi-pH ye-7.3-8.7.
