3,4,5,6-Tetrabromophenolsulfonephthalein CAS: 77172-72-6

3,4,5,6-Tetrabromophenolsulfonephthalein (TBPSPT) yog ib qho xim sib xyaw uas siv los ua ib qho cim qhia hauv kev tshuaj ntsuam xyuas tshuaj. Nws cov nyhuv thiab kev siv feem ntau yog cuam tshuam nrog nws cov yam ntxwv hloov xim.

TBPSPT feem ntau siv los ua qhov qhia txog acid-base vim nws muaj peev xwm hloov xim nyob ntawm pH ntawm cov tshuaj. Nws feem ntau yog xim liab ntawm pH qis (acidic conditions) thiab daj ntawm pH siab (basic conditions). Qhov kev hloov xim no tuaj yeem pab tau rau ntau yam kev siv, xws li titrations thiab pH determinations, qhov twg qhov kawg ntawm kev tshuaj tiv thaiv lossis acidity / alkalinity ntawm cov tshuaj yuav tsum tau txiav txim siab.

Tsis tas li ntawd xwb, TBPSPT tau siv rau hauv kev tshawb nrhiav ib puag ncig, tshwj xeeb tshaj yog rau kev nrhiav pom cov reactive oxygen species (ROS). Thaum raug rau ROS, xws li hydroxyl radicals lossis singlet oxygen, TBPSPT hloov xim, muab qhov pom tseeb ntawm qhov muaj cov reactive species no.
