High ionic strength dye baths distort glass electrode pH readings through activity shifts and liquid junction potential offsets that demand matrix-matched buffer calibration.
Automated potentiometric titration using double-junction glass electrodes resolves active hydroxide and carbonate alkalinity in high-salinity reactive dye baths.
Potentiometric control of high-concentration sodium hydroxide liquors requires matrix-matched calibration and derivative titration to correct sodium error and junction potential.
Uncorrected reference junction potentials in high-alkali dye baths cause hidden pH offsets up to 0.4 units, driving dye hydrolysis and shade off-tones.
High sodium ionic strength distorts electrochemical probe signals in mercerization baths, requiring Pitzer activity corrections to prevent quality defaults.
