A colorimetric method was worked out to determine negligible amounts of arsanilic acid, based on the property of amino groups to form a yellow stained Schiff base in the interaction with an acid solution of p-dimethyl- aminobenzaldehyde. The optic density of the coloured solution in methanol is determined at 450 nm. The presence of the A, D3, C, K3 vitamins, furazolidon, neomycin sulphate, and tylosine phosphate does not interfere with the determination of arsanilic acid.
基于氨基与对二甲基氨基苯甲醛酸溶液相互作用形成黄色 Schiff 碱的性质，制定了一种比色法来测定微量的对氨基苯胂酸。在 450 nm 处测定甲醇中有色溶液的光密度。维生素 A、D3、C、K3、呋喃唑酮、硫酸新霉素和磷酸泰乐菌素的存在不干扰对氨基苯胂酸的测定。
