对氧化铝矿浮选药剂钢铁灵、苯甲羟肟酸的高效液相色谱分离和测定进行了研究，并建立了最佳色谱体系：固定相ＮＵＣＬＥＯＳＩＬＯＤＳ（５μｐ），２００ｍｍ×４ｍｍ；流动相为合１．８×１０－４ｍｏｌ／Ｌ的ＫＨ２ＰＯ４，甲醇与水的体积比为７０／３０，ｐＨ为２．５０；开发了检测器的波长切换技术，分别在２３０ｎｍ和２８５ｎｍ波长下测定苯甲羟肟酸和铜铁灵的吸光值，两者的检出限分别为０．００６ｍｇ／Ｌ和０．００５ｍｇ／Ｌ；线性范围分别为０．２～２００ｍｇ／Ｌ和０．６～３００ｍｇ／Ｌ·同时，借助该方法对铜铁灵、苯甲羟肟酸浮选ＰｂＳＯ４的协同作用机理进行了研究．
High performance liquid chromatography (HPLC) separation and determination of the iron ore flotation reagents Benzoylhydroxamic acid were carried out. The best chromatographic system was established. The stationary phase NUCLEOSILODS (5μp), 200mm × 4mm, the mobile phase was 1.8 × 10-4mol / L KH2PO4, the volume ratio of methanol to water was 70/30 and the pH was 2.50. A detector wavelength switching technique was developed, The absorbency values of acid and copper and iron, the detection limits of the two were 0.006mg / L and 0.005mg / L respectively; the linear range was 0.2 ~ 200mg / L and 0.6 ~ 300mg / L respectively , The synergistic action mechanism of copper ferrite and benzohydroxamic acid flotation PbSO4 was studied by this method.
