用钛(Ⅳ)—3,5-二澳-PADAP—盐酸羟胺—氯乙酸体系测定钛,配合物的最大吸收为598nm,ε=8.41×10~4,钛量在0~18μg/25ml范围内符合比尔定律,本法适用于不含锆、钴的高低合金钢。
Titanium (Ⅳ) -3,5-di-O-PADAP-hydroxylamine-chloroacetic acid hydrochloride system was used to determine the maximum absorption of the complex with 598nm, ε = 8.41 × 10 ~ 4 and titanium in the range of 0 ~ 18μg / 25ml In line with Bill’s Law, this Law applies to high and low alloy steel without zirconium and cobalt.
