| Abstract: | This paper reports on an improvement on the method of using PAN asan indicator in assaying aluminum, which involves adding non-ionicsurfactantTritonx-100 and results in sensitive endpoint discolouration, greater contras-tiveness, quicker reaction, and greater sensitivity and accuracy of the assay. |
