Isicelo

I-Alpha Nephthophyllein isetyenziswa njengesalathisi se-asidi. Ayinambala ukuya kotyheli orenji kwi-pH emalunga ne-6.7 kwaye itshintsha ukusuka kotyheli orenji ukuya koluhlaza okwesibhakabhaka kwi-pH emalunga ne-7.9. Ukungcola kwiimveliso ezithengiswayo kudla ngokubonakala njengombala obomvu okhanyayo, otshintsha ukusuka kobomvu okhanyayo ukuya koluhlaza okwesibhakabhaka kwi-pH ye-7.3-8.7.
