Abstract：
The glass particles were coated with Spirulina sp. LEB-18 and bioblends of Spirulina sp. LEB-18/chitosan by casting technique and, afterward, it was verified its potential as adsorbents for basic and acid dyes. Nine Spirulina sp. suspensions with different components were used to coat the glass particles, and in the best condition of coating were prepared the bioblends with chitosan. The coated glass particles with Spirulina sp. and its bioblends with chitosan were applied in adsorption of the allura red (acid) and methylene blue (basic) dyes in a batch operation evaluate the pH effect, and a fixed bed column operation, being evaluated to the removal percentage and adsorption capacity of the column. The glass particles coated with Spirulina sp. applied in batch adsorption showed the highest removal percentages for allura red dye (35 to 45%) at pH 4.0, and for methylene blue dye (35 to 80%) at pH 6.0 and 8.0. In fixed bed column using glass particles coated with bioblends were reached the amount dye of 54.2 mg of adsorbed allura red dye and 60.2 mg of the of adsorbed methylene blue dye, respectively. Moreover, it was found good dye adsorption capacities, around 89 mg g-1, for both dyes, in acidic and basic pH values. Based on these results, these bioblends coated glass particles can be applied as an adsorbent for different types of dyes in adsorption column.
摘要：
用螺旋藻包被玻璃颗粒。LEB-18和螺旋藻的生物。LEB-18/壳聚糖通过铸造技术和，之后,它被证实了其作为碱性和酸性染料吸附剂的潜力。九号螺旋藻sp.具有不同成分的悬浮液用于涂覆玻璃颗粒，并在最佳包衣条件下制备了壳聚糖生物共混物。涂有螺旋藻的玻璃颗粒。并将其与壳聚糖的生物共混物应用于成批操作中对诱惑红（酸性）和亚甲基蓝（碱性）染料的吸附，和固定床柱操作，对色谱柱的去除百分比和吸附能力进行评价。涂有螺旋藻的玻璃颗粒。在分批吸附中应用显示，在pH4.0时，对诱惑红染料（35至45％）和在pH6.0和8.0时，对亚甲基蓝染料（35至80％）的去除率最高。在固定床色谱柱中使用涂有双亲的玻璃颗粒获得的染料量为54.2mg吸附的诱惑红染料和60.2mg吸附的亚甲基蓝染料，分别。此外，发现了良好的染料吸附能力，大约89毫克克-1，对于两种染料，在酸性和碱性pH值。基于这些结果,这些涂覆玻璃颗粒的双载体可用作吸附柱中不同类型染料的吸附剂。
