The present invention discloses a method for efficiently separating and enriching tin from nickel-tin-iron alloy scrap. The method comprises that: nickel-tin-iron alloy scrap is added into a metallurgy furnace, the material is subjected to mixing melting under a heating effect of the metallurgy furnace, a vulcanizing agent is blown into the melting pool through a spray gun after the material is subjected to complete melting so as to carry out a vulcanizing detinning reaction, the high temperature flue gas produced during the process is cooled, and the tin-containing flue dust is recovered. According to the present invention, characteristics of short process, low energy consumption, easy operation, and significant tin separation and enrichment effect are provided, and the qualified nickel-iron alloy raw material can be obtained; the characteristic that tin in the alloy scrap is easily subjected to vulcanizing volatilization is completely utilized, and the tin separation effect is significant; other impurity elements are not introduced in the melting pool, and the quality of the remaining nickel-iron alloy raw material is high; and the operation of the process is simple, and the promotion application prospect is good.

The invention provides a three-in-one molecular imprinted column capable of separating clenbuterol, salbutamol and ractopamine at the same time. The molecular imprinted column contains an imprinted polymer capable of respectively identifying and separating three molecules, namely the clenbuterol, the salbutamol and the ractopamine. A method for preparing molecular imprinted microspheres is to perform suspension polymerization in a water phase system, and obtained molecular imprinted polymer particles can be directly packed in the column for use without being ground and sieved.

The invention relates to a sulfonation method of natural zeolite for adsorption and recycling of rare earth ions. The method comprises the following steps of firstly, acidizing the natural zeolite, then conducting sulfhydrylation grafting on the surface of the acidized natural zeolite, oxidizing sulfydryl on the surface of the natural zeolite subjected to sulfhydrylation, and finally, acidizing the obtained product in an acidic solution so as to obtain the sulfonated natural zeolite. The sulfonated zeolite not only has the original high specific surface area of the zeolite but also has functional groups with chelation action, and can gather and separate the rare earth ion furthest under the synergistic effect of two different adsorption modes.
