ABSTRACT:
A three step flow injection analysis method for determining the degree of neutralization of phenol in solution. The first step is to flow a stream of a carrier liquid, such as water, along one side of a two sided semipermeable membrane, such as a silicone rubber membrane. The second step is to flow a stream of water along the other side of the membrane to a detector, such as a flow through ultraviolet spectrometer, the detector being responsive to the concentration of the phenol in the flowing stream of water. The third step is to add a volume of the solution to the flowing stream of carrier liquid so that the solution is carried to the first side of the membrane where a portion of the phenol permeates across the membrane into the flowing stream of water to be detected by the detector, the degree of neutralization of the phenol in the solution being a function of the response of the detector. The results of the method are substantially unaffected by variations in the concentration of the phenol.
