摘要：

Poly(vinylbenzyltriphenylphosphonium chloride) reacts more strongly with acidic dyes than quaternary ammonium salts such as zephiramine. This polymer can be used to improve the spectrophotometric determinations of lanthanum, aluminum, and beryllium when it is added to the binary La-xylenol orange, Al-pyrocatechol violet and Be-chromazurol S systems. The molar absorptivities for these systems are similar to those obtained with quaternary ammonium salts, but there are advantages of greater stability and lower reagent consumption. © 1979.
