Patent number: 9914111Abstract: The present invention relates to a mercury-containing wastewater treatment technology field, in particular to an attapulgite-crosslinked chitosan composite adsorbent and its solid-phase synthetic method. The attapulgite-crosslinked chitosan composite mercury adsorbent in the invention is synthesized by the method of adding chitosan and glutaraldehyde in batches. In consideration of the limited solubility of chitosan, batch addition can not only dissolve chitosan, but also minimize the use of organic acid, resulting in less discharge of wastewater and waste gas, which is suitable for large-scale industrial production. The prepared mercury adsorbent can be applied to the removal of mercury ions in the wastewater owing to the excellent adsorptive property and regeneration performance. Meanwhile, the solid-phase synthetic procedure for preparing the mercury adsorbent is simple, easy to handle and environmental-friendly. Moreover, the product cost is greatly reduced due to the use of attapulgite.Type: GrantFiled: March 17, 2017Date of Patent: March 13, 2018Assignees: Wuhu Gefeng Green Technology Research Center Co., Ltd., Shandong Wuzhou Detection Co., Ltd.Inventors: Xiangdong Feng, Menglu Shi, Wengui Zhang, Huanghe Wu, Weiwei Liang, Zhifeng Lan, Jian You, Changlu Zhang

Publication number: 20150133294Abstract: In one aspect, the present invention provides a chromatographic stationary phase material for various different modes of chromatography represented by Formula 1: [X](W)a(Q)b(T)c (Formula 1). X can be a high purity chromatographic core composition having a surface comprising a silica core material, metal oxide core material, an inorganic-organic hybrid material or a group of block copolymers thereof. W can be absent and/or can include hydrogen and/or can include a hydroxyl on the surface of X. Q can be a functional group that minimizes retention variation over time (drift) under chromatographic conditions utilizing low water concentrations. T can include one or more hydrophilic, polar, ionizable, and/or charged functional groups that chromatographically interact with the analyte. Additionally, b and c can be positive numbers, with the ratio 0.05?(b/c)?100, and a?0.Type: ApplicationFiled: May 15, 2013Publication date: May 14, 2015Applicant: Waters Technologies CorporationInventors: Kevin D. Wyndham, Michael F. Morris, Darryl W. Brousmiche, Jason F. Hill, Jacob N. Fairchild

Patent number: 9029290Abstract: The present invention relates to a composite of a porous substrate and one-dimensional nanomaterial, which is manufactured by a hydrothermal method. The method for manufacturing the composite of the present invention is simple and low-cost, and the one-dimensional nanomaterial is homogeneously distributed on the porous substrate with tight binding at the interface. The present invention also relates to a surface-modified composite and a method for preparing the same. The composite of the present invention which is hydrophobically modified at the surface can adsorb organic solvents such as toluene, dichlorobenzene, petroleum ether and the like, and greases such as gasoline, lubricating oil, motor oil, crude oil and the like, with a weight adsorption ratio of >10.Type: GrantFiled: August 14, 2012Date of Patent: May 12, 2015Assignee: City University of Hong KongInventors: Chunsing Lee, Shuittong Lee, Yongbing Tang, Mankeung Fung, Chiuyee Chan
