Liquid membrane emulsion and its usage

Abstract

The invention concerns a kind of milk liquid and its function. The milk liquid is mixing thing, including solution, coal oil, emulsify; solution is: some peiwei solution that can format the thing of larger than 10-15; the density is 0.01--0.1M. Liquid film is applied after the minerals attaching heavy metal. The milk liquid and its function can make minerals rebirth, absorb after attaching heavy metal ion.

Description

Technical field [0001] The present invention relates to the technical field of liquid film extraction, in particular to liquid film emulsions used in liquid film methods and uses thereof. Background technique [0002] Liquid membrane separation is an emerging extraction separation technology that has developed very rapidly in the past ten years, referred to as ELM technology. Because the liquid membrane separation technology has the advantages of high efficiency, speed, simplicity, energy saving, etc., at present, the technology has been extensively studied in aerospace, petroleum, metallurgy, environmental protection, medicine, biology, seawater desalination, chemistry and chemical engineering, and the electronics industry. The laboratory moves towards industrial production. For example, the article "Research on the Conditions of Extracting Rare Earths by Liquid Membrane Method" on pages 44-48 of "Guangxi Chemical Industry" Vol. 23, 1994 No. 1, discloses the application of liqui...

Problems solved by technology

However, these methods either require the introduction of other substances, or the pretreatment is complex; or the operation is cumbersome and difficult to master, especially the high cost of treatment, which brings difficulties to the implementation, and it is difficult to remove multiple heavy metal ions at the same time

[0004] In order to effectively eliminate heavy metal ions in sewage, people currently use the interface adsorption effect of mineral materials to treat wastewater containing heavy metal ions by adsorption. There are quite a lot of researches in this area at home and abroad, such as: Chinese Patent Publication No. CN1194238A , the published "Methods for Removing Heavy Metals from Industrial Wastewater", etc. Although these methods have achieved good water treatment effects, if the mineral materials that have absorbed heavy metal ions are not regenerated, they will cause secondary pollution

[0005] At present, the regeneration of mineral materials at home and abroad mainly uses chemical reagents such as acid, alkali, and salt, or methods such as strong heat, magnetic field, and microwave. reuse
