[0011] Sieve 100 g through a 12-mesh weight sieve to obtain ramie bone sawdust, select 300 mL of 30% NaOH solution, and carry out alkalization treatment at room temperature for 3 hours to obtain alkaline ramie bone. Then the prepared alkaline ramie bone 50g was added into 300mL isopropanol respectively with 40mL concentration of 30% (w / v) NaOH solution and 90g concentration of 50% (w / v) 3-chloro-2-hydroxy Propyltrimethylammonium chloride was reacted at 30°C for 1 h, after the reaction, the pH was adjusted to neutral with 10% hydrochloric acid, washed, suction filtered, and dried.

[0012] The prepared ramie bone adsorbent (1g) and 0.5g / L reactive brilliant red...

Embodiment 2

[0014] The ramie stalk sawdust (1g) obtained by sieving through a 12-mesh weight sieve after crushing is packed in an adsorption column (diameter 2cm), and the reactive brilliant red X-3B solution (50ml) of 0.5g / L is passed from the bottom of the adsorption column , use a peristaltic pump to pump the dye liquor wastewater at the bottom of the adsorption column to the top of the adsorption column to form a reflux, the adsorption time is 60min, and the adsorption rate is only 11%.

[0015] Sieve 100 g through a 12-mesh weight sieve to obtain ramie bone sawdust, select 300 mL of 30% NaOH solution, and carry out alkalization treatment at room temperature for 3 hours to obtain alkaline ramie bone. Then the prepared alkaline ramie bone 45g was added into 300mL isopropanol respectively with 45mL concentration as 30% (w / v) NaOH solution and 100g concentration as 50% (w / v) 3-chloro-2-hydroxy Propyltrimethylammonium chloride was reacted at 30°C for 1 h, after the reaction, the pH was ad...

Embodiment 3

[0018] The ramie stalk sawdust (1g) obtained by sieving through a 12-mesh weight sieve after crushing and the active bright orange K-GN solution (50mL) of 0.6g / L were added to the steel cup of the rotary infrared dyeing machine for adsorption (adsorption Time 70min, temperature 40 ℃), its adsorption rate is only 10%.

[0019] Sieve 100 g through a 12-mesh weight sieve to obtain ramie bone sawdust, select 300 mL of 30% NaOH solution, and carry out alkalization treatment at room temperature for 3 hours to obtain alkaline ramie bone. Then add 50mL concentration of 30% (w / v) NaOH solution and 110g concentration of 50% (w / v) 3-chloro-2-hydroxyl in 300m isopropanol to the prepared alkaline ramie bone 40g Propyltrimethylammonium chloride was reacted at 30°C for 1 h, after the reaction, the pH was adjusted to neutral with 10% hydrochloric acid, washed, suction filtered, and dried.

Abstract

The present invention discloses a ramie bone absorption agent adopted as an absorption agent, and a preparation method thereof. The preparation method comprises: removing sediment impurities from 100 g of ramie bone, crushing by using a crusher, screening through a 12 mesh sieve to obtain ramie bone chips, selecting 300 mL of a NaOH solution with a concentration of 30% to carry out an alkalization for 3 h at a room temperature to prepare alkaline ramie bone, adding the prepared alkaline ramie bone to a mixed solution to carry out reaction for 1-3 h at a temperature of 30 DEG C, adjusting the pH value by using 10% hydrochloric acid until the solution is neutral, and carrying out washing, suction filtration and drying, wherein 40-75 mL of a 30% NaOH solution and 90-110 g of 3-chloro-2-hydroxypropyltrimethylammonium chloride with a concentration of 50% are respectively added to 300 mL of isopropyl alcohol to obtain the mixed solution. According to the present invention, raw material cost is low, raw materials are environmentally friendly, and test results show that absorption efficiency on a dye solution achieves 99%, an absorption amount is large, an absorption effect is good, and absorption ability is strong.

Description

technical field [0001] The invention relates to an adsorbent, in particular to a ramie bone adsorbent used as an adsorbent and a preparation method thereof. Background technique [0002] Ramie bone is a by-product left over from the extraction of ramie fibers. my country is the country with the largest ramie planting area in the world, with an output of 4 million mu at the peak, accounting for more than 90% of the world's ramie output. However, the ramie industry in my country mainly uses ramie bast to process ramie yarn, and about 2.88 million tons of ramie stalks are discarded in the field. There are few studies on the application of ramie stalks. Zheng Ruixian et al. (Zheng Ruixian, Li Niancun, Han Jian. Development of ramie bone fiberboard. Journal of Hunan Agricultural College, 1989, 15: 149-153.) studied the processing of ramie stalks into The possibility of fiberboard, but no industrial production. Zeng Qingfu et al. (1. Zeng Qingfu, Cui Yongming, Chen Wu, Chen Hon...
