1. A metal extractant comprising a 2-hydroxyphenyldiazole compound according to Formula (2)wherein
R5 is selected from the group consisting of hydrogen, an optionally substituted C1-C36 hydrocarbyl group, halogen, and nitro; R7 is chosen from hydrogen or an optionally substituted C1-C36 hydrocarbyl group; each of R9 and R10 is independently selected from the group consisting of hydrogen, an optionally substituted C1-C36 hydrocarbyl group, an optionally substituted C1-C36 hydrocarbyloxy group, an optionally substituted C1-C36 hydrocarbyloxycarbonyl group, an optionally substituted C1-C36 hydrocarbylcarbonyloxy group, and an optionally substituted C1-C36 mono- or dihydrocarbylaminocarbonyl group;and tautomers or salts thereof, with the proviso that:
when R7 is H or C1-C5, then at least one of R9 or R10 is selected from the group consisting of an optionally substituted C9-C36 hydrocarbyl, C1-C36 alkoxy, C1-C36 hydrocarbyloxycarbonyl, C1-C36 hydrocarbylcarbonyloxy, and C1-C36 mono- or dihydrocarbylaminocarbonyl.
