摘要：

Mixtures of La3+ and Ni2+ ions form with Alizarin Fluorine Blue (1,2-dihydroxyanthraquinon-3-ylmethylamine-N,N-diacetic acid; AFB) the ternary complex (AFB)2La. Nin- which has maximum light absorption at 550 nm (ε{lunate} = 1.13 × 104); Kcond = 1.9 × 105 lṁole-1 at pH 4.5 and 25°, ionic strength = 0.1. The use of this complex for the photometric determination of nickel has been investigated. © 1969.
