微量元素钼的测定和钼酸锂的缓蚀研究

Determination of Molybdenum and Study on Corrosion-inhibition of Lithium Molybdate

用EDTA滴定法测定了钼酸盐中的钼含量．用重量法研究了钼酸锂对炭钢的缓蚀能力。结果表明，当pH4时，0．02％～0.07％钼酸锂对A3钢片的援蚀力为36．0％～74.8％。

A rapid testing meThod for the detendnation of molybdenutn in alkali molybdates byEDTA titration is presented. The ability of lithium molybdate as a corrision inhibitor in absorption refrigeration is Prelidriry confirmed. The optimal concentration is between the region of 0.02% ～0. O7% lithium molybdate, in which the percentages of corrosioninhibitionare about 36. 0% t0 74. 8% in 55% lithium bromide solution (pH4) 。
