Embodiment 1

[0032] Weigh 100g of LX68M resin, put it in a 500ml beaker, measure 100ml of absolute ethanol, add it to the resin, stir for 10 minutes, and place it for 2 hours.

[0033] The resin was filtered and the ethanol was discarded. Put the resin in a 1000ml beaker, add 100ml of purified water, stir for 10 minutes, let stand for 1 hour, filter, and discard the water. According to the above steps, wash the resin twice with 100ml and 100ml of water respectively, filter, discard the water, and reserve the resin for later use.

[0034] The washed resin was placed in a 500ml beaker, 100ml of 5% hydrochloric acid solution was measured, added to the resin, stirred for 10 minutes, and left for 3 hours. Filter and discard the hydrochloric acid solution. Resin spare.

[0035] Weigh 5 g of barium chloride, 2 g of strontium sulfate, 10 g of ferrous chloride, 2 g of rubidium oxide, and 1 g of zirconium oxide. Place in a 500ml beaker and stir to mix.

Embodiment 2

[0040] Weigh 100g of LX68M resin, put it in a 500ml beaker, measure 200ml of absolute ethanol, add it to the resin, stir for 10 minutes, and place it for 2 hours.

[0041] The resin was filtered and the ethanol was discarded. Put the resin in a 1000ml beaker, add 100ml of purified water, stir for 10 minutes, let stand for 1 hour, filter, and discard the water. According to the above steps, wash the resin twice with 100ml and 100ml of water respectively, filter, discard the water, and reserve the resin for later use.

[0042] The washed resin was placed in a 500ml beaker, 150ml of 5% hydrochloric acid solution was measured, added to the resin, stirred for 10 minutes, and left for 1 hour. Filter and discard the hydrochloric acid solution. Resin spare.

[0043] Weigh 10 g of barium chloride, 4 g of strontium sulfate, 20 g of ferrous chloride, 4 g of rubidium oxide, and 2 g of zirconium oxide. Place in a 500ml beaker and stir to mix.

Abstract

The invention provides an adsorbent for enriching polyunsaturated fatty acids and ester products thereof. The preparation method is characterized by comprising the following steps: firstly, putting macroporous resin into absolute ethyl alcohol for soaking and filtering; secondly, washing the macroporous resin with water and filtering; thirdly, adding hydrochloric acid into the macroporous resin for soaking; fourthly, mixing barium chloride, strontium sulfate, ferrous chloride, rubidium oxide and zirconium oxide to form a solid mixture; fifthly, adding the hydrochloric acid into the solid mixture and dissolving to obtain a mixed solution; sixthly, adding the treated macroporous resin into the mixed solution and filtering; and seventhly, carrying out vacuum drying on the macroporous resin treated in the sixth step to obtain a final product. The adsorbent can selectively adsorb the polyunsaturated fatty acids and ester products thereof and can be used for multiple times.

Description

technical field [0001] The invention relates to an adsorbent and its preparation method and use, in particular to an adsorbent enriched in polyunsaturated fatty acids and their ester products, its preparation method and use. Background technique [0002] Polyunsaturated fatty acid (PUFA) refers to a straight-chain fatty acid containing two or more double bonds and a carbon chain length of 18 to 22 carbon atoms. It is usually divided into omega-3 and omega-6. In polyunsaturated fatty acid molecules, the double bond farthest from the carboxyl group is called omega-3 on the penultimate third carbon atom; on the sixth carbon atom , it is called omega-6. It is synthesized by aquatic phytoplankton in cold regions and helps reduce cardiovascular and cerebrovascular diseases. It has the following functions: 1. Maintain the relative fluidity of the cell membrane to ensure the normal physiological functions of the cells. 2. Esterify cholesterol, lower blood cholesterol and triglyce...
