镍具有良好的抗蚀性、韧性和机械强度、磁性以及较高的化学稳定性,被广泛地应用于钢铁工业、国防工业、冶金工业、化学工业、陶瓷工业、电子工业、原子能工业和电镀工业。近代工业技术的发展,无论对测镍的精度、灵敏度和速度均提出很高要求。十多年来,镍的分析技术有了很大的发展。一、重量法十多年来,对丁二肟重量法测镍的条件作了很多改进,从而简化了流程,提高了精度,扩大了应用范围。如Byru和Robertson用N,N-二羟基乙烯基甘氨酸有效地消除了铁、钴干扰,
Nickel has good corrosion resistance, toughness and mechanical strength, magnetic properties and high chemical stability. It has been widely used in iron and steel industry, defense industry, metallurgical industry, chemical industry, ceramics industry, electronics industry, atomic energy industry and electroplating industry . The development of modern industrial technology, regardless of the accuracy of nickel, sensitivity and speed are put forward high requirements. For more than a decade, nickel analysis technology has greatly developed. First, the gravimetric method For more than a decade, the conditions for the determination of the weight of nickel dioxime have made many improvements, thus simplifying the process and improve the accuracy and expand the scope of application. Such as Byru and Robertson with N, N- dihydroxyvinyl glycine effectively eliminate the iron and cobalt interference,
