Embodiment 1

[0027] The adsorbent material of the present invention is prepared according to the following steps:

[0028] 1. According to the ratio of the cation exchangeable amount (molar number) of sodium bentonite to the molar ratio of polyepichlorohydrin dimethylamine, 41 grams of polyepichlorohydrin dimethylamine (purchased from Zibo Sanfu Chemical Development Co., Ltd.) and 53 grams of sodium bentonite (purchased from Zhejiang Fenghong Clay Chemical Co., Ltd.) were added to the three-necked flask, and 300 ml of deionized water was added, keeping the temperature at 90 ° C, and stirring the mixture to make it The reaction was carried out for 2 hours to obtain a slurry product;

[0029]2. Transfer the prepared slurry product to a beaker, and add 20-30 mesh activated carbon particles (ZJ-238, Jiangsu Liyang South Activated Carbon Factory) into it, so that the activated carbon particles are completely covered by the above slurry;

[0030] 3. Dry the product obtained in step 2 for 4 hour...

experiment example 1

[0033] according to figure 1 In the flow shown, the adsorption capacity and effect of the adsorption material are determined by the chromatographic column evaluation method. Chromatographic column 5 is made of glass, with a diameter of 3 cm and a length of 70 cm. Specific steps are as follows:

[0034] 1. Pack the 8-30 mesh composite adsorption material of the present invention prepared in Example 1 into the chromatographic column 5;

[0035] 2. Power on the peristaltic pump 3, open the cut-off valve 2, use the peristaltic pump 3 to pass the test aqueous solution with an oil content of 1000 ppm in the monosodium glutamate mother liquor tank 1 through the flow meter 4, press it in from the upper part of the chromatography column 5, and after being adsorbed by the adsorption column 5 The water flow is discharged through the shut-off valve 6; and it flows out from the bottom of the chromatographic column 5, and the flow of the aqueous solution is controlled so that its residenc...

Abstract

The invention provides an adsorption discoloring material for monosodium glutamate mother liquor. The adsorption discoloring material comprises a first adsorbing material and another adsorbing material coated at the periphery of the first adsorbing material and is characterized in that the first adsorbing material is integrally of a reticular porous structure, and the aperture range is smaller than 20 nm; and the other adsorbing material is integrally of a template-shaped multilayer structure, and the spacing among the crystal layers is 5-50 nm. The organic load amount of the adsorption decolorizing material for the monosodium glutamate mother liquor is 100-200 mg / g, and the specific area is 20-100 m<2> / g; and after the pigment in the monosodium glutamate mother liquor is removed, the transmittance of the mother liquor reaches more than 90%, and the removal rate of colloids and suspended matters reaches more than 90%.

Description

technical field [0001] The invention relates to a water treatment material, in particular to a material for adsorption and decolorization of monosodium glutamate mother liquor. Background technique [0002] At present, in the production of monosodium glutamate, the fermentation method is the main method at home and abroad. Due to factors such as impurities in the raw materials and equipment corrosion, inorganic pigments such as Fe2+ and Fe3+ often exist in the glutamic acid neutralization solution, and both are produced by protein fermentation. Pigment - Among them, organic pigments of weak acids are the main ones, and they have the characteristics of relatively large molecular weight. In the refining production process, since the raw material (glutamic acid) contains more pigments, it will inevitably be brought into the MSG mother liquor. If it is not treated, it will seriously affect the product quality of MSG. In the existing production process, the monosodium glutamate ...
