Abstract

Glycolurils are building blocks for cucurbiturils. Poly(glycoluril-formaldehyde) produced microparticles, which were synthesized for the first time by the combination of glycoluril and formaldehyde. Poly(glycoluril-formaldehyde) microparticles were characterized by SEM, XRD and FTIR. The porosity of these microparticles were examined using N₂ absorption – desorption studies, which indicated the non-porous nature of the material. However, these microparticles behaved same as cucurbiturils with respect to dye removal studies. Unlike the cucurbiturils, these microparticles were easy to prepare with no purification steps involved. Furthermore, these microparticles facilitated to remove the environmental pollutants such as dyes, hair dyes, antibiotic drug and inorganic compounds. These microparticles also aided to purify the urine samples and eliminated the RBC cells from the cow urine samples effectively.

聚乙二醇甲醛微粒子用于环境污染物的修复

糖醛酸是葫芦醛酸的组成部分。聚乙二醇-甲醛合成微颗粒，首次将乙二醇-甲醛合成。采用扫描电镜（SEM）、x射线衍射（XRD）和红外光谱（FTIR）对聚乙二醇甲醛进行了表征。用氮气吸附-解吸法检测了这些微粒的孔隙度，表明了材料的非多孔性。然而，这些微粒在染料去除研究方面的表现与葫芦素相同。与葫芦素不同的是，这些微粒很容易制备，不需要提纯步骤。此外，这些微粒还有助于去除染料、染发剂、抗生素、药物和无机化合物等环境污染物。这些微粒还有助于净化尿液样本，并有效地消除牛尿液样本中的红细胞。

期刊介绍： The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
