The extraction equilibrium and kinetics of galium(III) from hydrochloric acid solutions with 1-phenyl-3-methyl-4-benzoyl-pyrazolone-5-(HPMBP) in carbon tetrachloride have been investigated. The composition of the extracted species was found to be Ga(PMBP)3.2H2O via the method of slopes, IR and NMR spectra. The values of Kex, ΔH ⅲ, ΔGⅲ and ΔSⅲ at 298K were calculated. The extraction kinetics of Ga(III) was studied with the growing drop method. The extraction rate equation can be expressed as Rf=kf[Ga^3^+][HL](o). The activation energy of the reaction was calculated to be 15.9kJ.mol^-^1. The rate determing step was deduced to take place in water phase: Ga^3^++HL→ GaL^2^++H^+, which is an immediate coordination process.
