1斜投影-不展开薄层色谱法对废木料液化产物乙酰丙酸的过程分析显示文摘采用多波长薄层色谱扫描法,不经过传统的薄层色谱展开步骤实现混合体系的快速定量。废木料液化过程产物为混合体系,分别将不同液化反应时间点所取样品点样于硅胶板上。仅对液化过程终点的样本点进行一次展开,分离斜投影建模所需的反射光谱,切割出目标产物(乙酰丙酸)和背景光谱,构造斜投影算子;对其他液化过程中的样品点不展开,采集混合光谱,经斜投影算法分离出其中的目标产物纯光谱,从而实现定量。将该方法的定量结果与高效液相色谱法的定量结果对比,得到两种方法测定乙酰丙酸的相对误差小于3.27%,表明两种方法具有良好的一致性。粟晖 葛军 方凤 姚志湘 宋光均 2014色谱2014,32,1:3
2Development of Eggshell Waste Incorporated with a Porous Host as a Humidity Adsorption Material显示文摘The duck eggshell waste was developed to the novel desiccant that is friendly to human and environment.The calcium oxide(Ca O)and calcium chloride(CaCl_(2))as the calcium-based desiccants were prepared from eggshell waste.The Ca O desiccant derived from the eggshell waste sintering at 1300℃,while the CaCl_(2)desiccant was extracted from eggshell waste with the hydrochloric(HCl)solution at difierent concentrations from 5 to 30 wt%.The yield percentage of CaCl_(2)desiccant increased with increasing the HCl concentration to 25 wt%.The humidity adsorption behavior were investigated in the range of 75%-5%relative humidity.The results show the CaCl_(2)desiccant has the highest hydration rate.The porous host from the kaolin was sintered at different temperatures from 200 to 1000℃and incorporated with 30%w/v concentrations of CaCl_(2).The physical properties and the humid-adsorption capacity of all porous host conditions were investigated.The porous host at sintering temperature 800℃has the highest specific surface area.Moreover,the porous host at sintering temperature 800℃with the 30%w/v concentration of CaCl_(2)desiccant has the highest humid-adsorption capacity.BOONSOOK Kanokwan NAEMCHANTHARA Patcharin LIMSUWAN Pichet NAEMCHANTHARA Kittisakchai 2023Journal of Wuhan University of Technology(Materials Science)2023,38,5:0
