摘要：
Recovery of metal ions [Cu(II), Co(II), Ni(II), Zn(II), Fe(III), Cr(III), Cr2O72-, and VO3-] from model solutions and actual wastewaters by flotation with octanoic acid hydrazide C7H15CONHNH2 and a crude mixture of hydrazides with R = C6H13-C8H17 (Gidrazeks-79M) was studied. A possible mechanism is proposed for interaction of metal ions with hydrazides.
