pH– ISIHLAZIYI SEXABISO LE-PH EMANZINI

UMGAQO WOKUSEBENZA

Isiseko sokumisela kukutshintsha kombala wesalathisi m-Cresol purple ngokuxhomekeke kwisampulipHixabiso. Kwimilinganiselo nganye, kufakwa umthamo omncinci wedayi yesalathisi kumjelo wesampuli apho ixabiso le-pH limiselwa khona nge-VIS absorption spectrometry.

IINZUZO

Ukulinganisa ixabiso le-pH kusetyenziswa i-m-Cresol purple yindlela yokulinganisa epheleleyo. Xa idibene nokusetyenziswa kobugcisa, le analyzer ayina-calibration kwaye ngoko ke ifanelekile ukusetyenziswa kwexesha elide. Ngaphezu koko, i-analyzer ingasetyenziselwa ukujonga umz. iinkqubo ze-biogeochemical zexesha elifutshane.
Ukusetyenziswa kwe-reagent ephantsi kwenza kube nokwenzeka ukuba kusetyenziswe ixesha elide ngaphandle kwemfuneko yokugcinwa kakhulu. Xa i-analyzer iphelelwe zii-reagents, iikhatriji zinokutshintshiswana ngokulula ngenxa yoyilo lwazo olulula ukulusebenzisa. Ukongeza, ukusetyenziswa kwesampulu ephantsi kwenza ukuba kumiselwe i-pH ukusuka kwizambuku ezincinci zesampulu.
