mg/g;PTCC对阳离子染料的吸附过程符合Lagergren二级吸附动力学方程,吸附速率常数k2随着温度的降低而升高,低温有利于吸附反应的进行;吸附过程ΔG、ΔH和ΔS均为负值,表明该吸附是自发的放热过程,主要是通过范德华力实现的. 吸附过程的吸附等温模型符合Langmuir等温式,可以用单分子层吸附理论加以解释.","authors":[{"authorName":"王亚伟","id":"0b393206-3fce-4fa9-bb92-8f5bab3d88e8","originalAuthorName":"王亚伟"},{"authorName":"施文健","id":"f603eb94-937f-4b0e-a484-173fd535bde5","originalAuthorName":"施文健"},{"authorName":"陈轩","id":"510faad5-bab2-43a4-8093-9573cf0116c2","originalAuthorName":"陈轩"},{"authorName":"韩悦","id":"be080d23-dd9f-4d3a-a8cd-ad03ab3deca1","originalAuthorName":"韩悦"},{"authorName":"杨琴淋","id":"ed3a6f7c-7bd2-4c2d-a25e-14a6b4926f38","originalAuthorName":"杨琴淋"},{"authorName":"周艳","id":"703dfae2-3584-4343-872d-abff70630178","originalAuthorName":"周艳"}],"doi":"10.3724/SP.J.1095.2010.90668","fpage":"817","id":"dc2a9416-a054-448f-af69-4d04fc5f1c16","issue":"7","journal":{"abbrevTitle":"YYHX","coverImgSrc":"journal/img/cover/YYHX.jpg","id":"73","issnPpub":"1000-0518","publisherId":"YYHX","title":"应用化学"},"keywords":[{"id":"64223c57-98c8-4e3d-b10e-d5473b00bafe","keyword":"纤维素","originalKeyword":"聚硫醚纤维素"},{"id":"b631b8a1-24ce-4827-86d6-28c275b95ac1","keyword":"阳离子染料","originalKeyword":"阳离子染料"},{"id":"cd885469-8f53-4410-8b13-9886504be9d9","keyword":"吸附","originalKeyword":"吸附"},{"id":"f35bee9b-44f1-489d-941b-e70da21f644b","keyword":"热力学","originalKeyword":"热力学"},{"id":"f57cf7a1-ead8-4434-96ea-bc0f07154af7","keyword":"动力学","originalKeyword":"动力学"}],"language":"zh","publisherId":"yyhx201007015","title":"纤维素吸附阳离子染料的动力学与热力学","volume":"27","year":"2010"},{"abstractinfo":"本文分析了纤维素的种类及其在干混砂浆的主要作用和保水性、粘度、粘结强度等性能评价方法,阐述了纤维素在干混砂浆中的缓凝机理、微观结构及某些特定薄层纤维素改性砂浆的结构形成与水化过程的关系,在此基础上,提出必须加快研究在快速失水条件下,薄层结构中纤维素改性砂浆的分层水化机理及聚合物在砂浆层的空间分布规律,未来在实际应用中应充分考虑纤维素改性砂浆受温度变化的影响、与其它外加剂的相容性等,本研究工作将促进CE改性砂浆如外墙抹灰砂浆、腻子、勾缝砂浆等薄层砂浆的应用技术发展.","authors":[{"authorName":"蹇守卫","id":"175c1859-a808-44d3-a273-b18f15283520","originalAuthorName":"蹇守卫"},{"authorName":"马保国","id":"07c326aa-0a2e-461d-bf0d-9e09b2d2ba71","originalAuthorName":"马保国"},{"authorName":"苏雷","id":"b85780d3-66bd-4fef-920f-fcdcd74039f3","originalAuthorName":"苏雷"},{"authorName":"李相国","id":"91f056c1-b8a2-4e54-9d70-c4caee4c73ad","originalAuthorName":"李相国"},{"authorName":"穆松","id":"0bccd56a-22bb-4549-9383-860c8d99d8e9","originalAuthorName":"穆松"},{"authorName":"袁龙","id":"2e241e3e-5ae0-4c95-9480-f04e48e6d4e6","originalAuthorName":"袁龙"}],"doi":"","fpage":"560","id":"669ff49b-1492-4f8d-8f7a-bf4b649bd8cb","issue":"3","journal":{"abbrevTitle":"GSYTB","coverImgSrc":"journal/img/cover/GSYTB.jpg","id":"36","issnPpub":"1001-1625","publisherId":"GSYTB","title":"硅酸盐通报
