A modified spectrophotometric method for selective determination of trace urea: application in the production process of ultrapure water
Conventional spectrophotometric methods were unable to accurately detect urea concentrations below 100 μg/L. A modified spectrophotometric method was developed to determine the trace urea in the ultrapure water (UPW) production process of the semiconductor manufacturing industry. This method was opt...
