Abstract Proposal No.: CTS-9618582 Proposal Type: GOALI Principal Investigator: Jan D. Miller Affiliation: University of Utah This grant is awarded through the Separations and Purification Program sub-element of the Interfacial, Transport and Separations Program of the Chemical and Transport Systems Division. The principal investigator is Jan D. Miller of the University of Utah. The research will be carried out by the University of Utah in collaboration with Shell Chemical Company. The objective of the proposed program is to adapt atomic force microscopy (AFM) to the determination of interparticle forces between particulate suspended in wastepaper deinking systems.(wastepaper pulping and deinking flotation systems). Importantly, the results from such research will establish the aqueous solution chemistry for effective deinking of wastepaper, particularly laser-printed and xerographic wastepaper's. On this basis, it is expected that a simple reliable and relatively inexpensive flotation technology can be developed. Technology development for the deinking of wastepaper, particularly laser-printed and photocopied office waste, has become an important environmental and process issue for the paper recycling industry. The development of a novel, inexpensive, and more efficient process for utilization of waste paper from modern printing processes is needed. Such development will be facilitated by fundamental surface chemistry research to establish a basis for technology innovation.

摘要 方案编号： CTS-9618582提案类型： GOALI主要研究者： 简·D米勒附属机构： 犹他州大学 该补助金通过化学和运输系统司界面，运输和分离计划的分离和纯化计划子要素授予。 主要研究者是Jan D。犹他州大学的米勒说。 这项研究将由犹他州大学与壳牌化学公司合作进行。 该计划的目的是适应原子力显微镜（AFM）的废纸脱墨系统中悬浮的颗粒之间的力的测定。（废纸制浆和脱墨浮选系统）。 重要的是，这些研究的结果将建立有效的废纸脱墨，特别是激光打印和静电复印废纸的水溶液化学。 在此基础上，有望开发出一种简单可靠且相对廉价的浮选技术。 废纸脱墨技术的发展，特别是激光打印和复印的办公室废物，已成为纸张回收业的一个重要的环境和工艺问题。 需要开发一种新的、廉价的和更有效的方法来利用来自现代印刷工艺的废纸。 基础表面化学研究将促进这种发展，为技术创新奠定基础。
