摘要

在气升反应器中对六种染料进行了吸附试验——四种阴离子染料(RR11、RB5、RB8和RR18)和两种阳离子染料(BV10和BG 4)以及三种吸附剂——壳聚糖片、壳聚糖珠状染料和壳聚糖固定化改性木屑(吸附剂3)。在所有进行的试验系列中，流入反应器的染料浓度为10 mg/dm3;吸附剂用量为10 g干物质(d.m./dm3)，流速为0.1 V/h。壳聚糖片的最大吸附量为3802 ~ 2203 mg/g d.m.，壳聚糖珠的最大吸附量为3312 ~ 2076 mg/g d.m.，壳聚糖固定化改性木屑的最大吸附量为2734 ~ 2148 mg/g d.m.。将木屑固定在壳聚糖上，对阴离子染料和阳离子染料均有较好的吸附效果。

USE OF CHITOSAN ADSORBENTS FOR DYE REMOVAL IN THE AIR-LIFT REACTOR

Adsorption tests in the air-lift reactor were carried out for six dyes – four anionic (RR11, RB5, RB8, and RR18) and two cationic (BV10 and BG 4) – as well as three adsorbents – chitosan flakes, chitosan in the form of beads, and modified sawdust immobilised in chitosan (adsorbent 3). The dye concentration in the inflow to the reactor in all the conducted test series was 10 mg/dm3; the amount of adsorbent was also constant at 10 g dry matter (d.m./dm3, and the flow rate was 0.1 V/h. For all tested dyes, the obtained maximum adsorption capacity was high and ranged from 3802 to 2203 mg/g d.m. for chitosan flakes, from 3312 to 2076 mg/g d.m. for chitosan beads, and from 2734 to 2148 mg/g d.m. for modified sawdust immobilised in chitosan. The immobilisation of sawdust on chitosan resulted in effective adsorption of both anionic and cationic dyes.
