摘要建议编号：CTS-9618582建议类型：GOALI首席研究员：简·D·米勒隶属关系：犹他大学这笔赠款是通过化学和运输系统司界面、运输和分离计划的分离和净化计划子要素授予的。首席研究员是犹他大学的简·D·米勒。这项研究将由犹他大学与壳牌化学公司合作进行。该计划的目标是采用原子力显微镜(AFM)来确定废纸脱墨系统(废纸制浆和脱墨浮选系统)中悬浮颗粒之间的颗粒间作用力。重要的是，这些研究结果将为废纸，特别是激光打印和静电打印废纸的有效脱墨建立水溶液化学。在此基础上，有望开发出一种简单、可靠和相对廉价的浮选技术。废纸，特别是激光打印和复印办公废纸的脱墨技术的发展，已经成为纸张回收行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现代印刷工艺中的废纸。这种发展将通过基础表面化学研究来促进，为技术创新奠定基础。

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.
