Abstract
Aluminum is present in practically all natural waters and may appear additionally in treated waters as a residual from alum coagulation. There is increasing evidence that very small amounts of aluminum, such as 0.05 mg/1, entering the distribution system can be objectionable. As a result, a recently proposed rapid eriochrome cyanine R(ECR) method for the determination of aluminum in water was tried and appeared to be at least as accurate as the aluminon method and less time consuming and complicated. This study was devised primarily to evaluate the ECR method and compare it with the existing aluminon standard method for aluminum in the presence and absence of interferences (fluorides, polyphosphates, and other metals).
