Embodiment 1
[0018] (1) Wash 5 grams of raw peach gum, remove impurities and add it to 100 milliliters of deionized water for soaking to make it fully swell, then use a beater to beat it into a slurry, and then put it in a condition where the pH is 11 Heated to 85°C under low temperature and stirred for 5 hours to obtain peach gum aqueous solution;
[0019] (2) add ferric chloride and ferrous chloride to the peach gum aqueous solution that step (1) makes, make the concentration of ferric chloride be 1 mol / liter, make the concentration of ferrous chloride be 0.5 mol / liter, Stir for 30 minutes to obtain an aqueous solution of peach gum containing iron salt;
[0020] (3) drop the peach gum aqueous solution containing iron salt that step (2) makes into 50 milliliters of concentrations and be in the aqueous ammonia solution of 8 mol / liter, promptly make magnetic peach gum.
Embodiment 2
[0022] (1) Clean 0.5 gram of raw peach gum, remove impurities and add it to 20 milliliters of deionized water for soaking to make it fully swell, then use a beater to beat it into a slurry, and then put it under the condition that the pH is 14 Heated to 95°C under low temperature, and stirred for 0.5 hours to obtain an aqueous solution of peach gum;
[0023] (2) add ferric chloride and ferrous sulfate in the peach gum aqueous solution that step (1) makes, make the concentration of ferric chloride be 0.1 mol / liter, make the concentration of ferrous chloride be 0.05 mol / liter , stirred for 2 minutes to obtain an aqueous solution of peach gum containing iron salt;
[0024] (3) the peach gum aqueous solution that step (2) makes contains iron salt is dripped in the sodium hydroxide aqueous solution that 5 milliliters of concentrations are 10 mol / liter, promptly makes magnetic peach gum.
Embodiment 3
[0026] (1) Clean 4 grams of raw peach gum, remove impurities and add it to 100 milliliters of deionized water for soaking to make it fully swell, then use a beater to beat it into a slurry, and then put it in the condition that the pH is 9 Heated to 70°C under low temperature and stirred for 6 hours to obtain peach gum aqueous solution;
[0027] (2) add ferric nitrate and ferrous gluconate in the peach gum aqueous solution that step (1) makes, make the concentration of ferric nitrate be 1 mol / liter, make the concentration of ferrous gluconate be 0.05 mol / liter, stir 120 Minutes, make the peach gum aqueous solution that contains iron salt;
[0028] (3) the peach gum aqueous solution that step (2) makes contains iron salt is dripped in the potassium hydroxide aqueous solution that 40 milliliters of concentrations are 0.2 mol / liter, promptly makes magnetic peach gum.

Abstract
The invention discloses a preparation method of magnetic peach gum, which comprises the following steps: cleaning the original peach gum, removing impurities, adding into deionized water, soaking until the peach gum is sufficiently swollen, beating into pulp through a beating machine, heating, and stirring to obtain a peach gum water solution; adding ferric iron salt and ferrous iron salt into the peach gum water solution, and stirring to obtain the peach gum water solution containing the iron salt; and adding the peach gum water solution containing the iron salt into alkali liquor to obtain the magnetic peach gum. The magnetic peach gum prepared by the invention has favorable magnetic property and adsorbability, and can be conveniently recovered from water by means of a magnet; the preparation process of the magnetic peach gum is very simple, and raw materials are accessible, thereby being suitable for large-scale preparation; and the magnetic peach gum has favorable application prospects in the aspects of dye and heavy metal adsorption, biological separation, magnetic catalysts and the like.
Description
technical field [0001] The invention relates to the field of functional natural polymer materials, in particular to a preparation method of magnetic peach gum. Background technique [0002] Peach gum is a colloidal translucent substance secreted from the trunks of Rosaceae plants such as peaches, mountain peaches, kiwis, and cherries; my country has very rich peach gum resources; the main component of peach gum is polysaccharides, which are composed of galactose, Composed of monosaccharides such as rhamnose, arabinose, and glucuronic acid, peach gum is non-toxic to humans and animals, and has high edible and medicinal value; commercial peach gum is also widely used in chemical, cosmetic, printing and dyeing, electronics and other industries . At present, the relevant research on peach gum is still in its infancy, and the research on magnetic peach gum has not been reported yet; in addition, magnetic polymer gel materials have shown good applications in industrial wastewater t...
