NOVELTY - Preparation of non-aqueous liquid phase complex iron-nano fluid, involves preparing non -aqueous solvent, adding ferric chloride and alkaline substance to obtain complex iron-non-aqueous solution, and adding nanoparticles. USE - Preparation of non-aqueous liquid phase complex iron-nano fluid for purifying and desulfurizing gas containing hydrogen sulfide (all claimed). ADVANTAGE - The complex iron-nano fluid has simple configuration, excellent desulfurizing rate, which is better than non-nano fluid of same concentration. The method is simple, low energy consumption and has mild reaction conditions.
