An ATR-UV Sensor for Simultaneous Monitoring of Sulfide, Hydroxide, and Carbonate in Kraft White Liquors During Mill Operations, 2002 Fall Technical Conference

This paper describes an ATR-UV sensor that provides rapid and simultaneous determination of sulfide, effective alkali, and carbonate in kraft white liquors. Simple linear calibration procedures were developed to ease quantitative analysis in mill operations. Two mill trials of the sensor were conducted and are reported in this study. The results of the three component concentrations show a good agreement between the ATR-UV method and the standard titration method. The ATR-UV technique is very simple to perform and can be used for on-line process control.
