Abstract
A high-selectivity cotton fibre adsorbent for the exhange of Fe carried ligand is prepared through preparing small cotton fibre beads, cross-linking between fibre beads and activating, and making the fibre beads functional. Its advantages are high exchange speed and power.
Description
(1) field under
The invention belongs to a kind of preparation of adsorbent method, particularly a kind of iron ligand exchange cotton fiber preparation of adsorbent method of carrying of high selectivity.
(2) background technology
In the middle of production practices and scientific experiment, particularly remove in the practice of arsenic from underwater,, have many shortcomings, such as 1. cost is higher though common adsorbent has the performance of ion-exchange; 2. exchange capacity is low; 3. exchange velocity is slow and be difficult for wash-out.
(3) summary of the invention
The objective of the invention is to prepare a kind of year iron ligand exchange cotton fiber adsorbent of high selectivity, make that above-mentioned shortcoming is overcome, can remove the trivalent arsenic in the underground water simultaneously well.
Technical scheme of the present invention is: a kind of iron ligand exchange cotton fiber preparation of adsorbent method of carrying of high selectivity is characterized in that it is to be made of following three steps: the 1. preparation of gossypin ball; 2. the crosslinked and activation of cellulose balls; 3. the functionalizing of gossypin ball.
The preparation of above-mentioned said gossypin ball is finished by following steps: the 1. preparation of alkali cotton; 2. the alkali cotton is aging; 3. the esterification of alkali cotton; 4. the preparation of gossypin ball; 5. gossypin ball pore.
Being prepared as follows of above-mentioned said gossypin ball: in 500 milliliters there-necked flask, the viscose that adds the 50-100 milliliter, cross the 2-7 gram calcium carbonate of 250 mesh sieves, stir, add the 100-200 decentralized medium then, disperse after 15-30 minute slow 80-100 ℃ of intensification, kept 2 hours with 2 ℃/min.React the room temperature of cooling, with the white of hot water injection's cellulose balls, promptly got the gossypin ball earlier.
Crosslinked and the activation of above-mentioned said cellulose balls is made of following step: 1. cellulose balls is crosslinked; 2. the activation of cellulose balls.
The cross-linking process of above-mentioned said cellulose balls is: get the wet ball of asking of cellulose after a certain amount of pore, the 1-3 1mol/LNaOH solution doubly that adds its volume, at stirred in water bath 20-30 minute, add a certain amount of epoxychloropropane, still at stirred in water bath 20-30 minute, be heated to 60-79 ℃ of reaction 20-40 minute then, reaction washes cellulose balls after finishing.
The activation method of above-mentioned said cellulose balls is: get the cellulose wet bulb of 10-20 milliliter after crosslinked, adding concentration respectively is 1-3mol/LnaOH solution 10-20 milliliter, with 3-4 milliliter epoxychloropropane, at room temperature to shake 24 hours, reaction finishes the thin clean cellulose balls in back.
Operation principle of the present invention is: this preparation comprises three processes, and order is: the 1. preparation of gossypin ball; 2. the crosslinked and activation of cellulose balls; 3. the functionalizing of gossypin ball.
Superiority of the present invention is: 1, exchange velocity is fast, and wash-out very easily; 2, exchange capacity is very strong.
