目的:采用星点设计-效应面优化法(CCD-RSM)研究D101型大孔吸附树脂同时分离纯化垂盆草复方中的总黄酮,总皂苷的工艺条件及参数.方法:以上样药液的浓度,洗脱液乙醇浓度和洗脱液用量为考察因素,以总黄酮解吸附率,总皂苷解吸附率,总黄酮纯度,总皂苷纯度及总评归一值(OD)为指标,采用多元线性回归及二次多项式拟合,建立...
1、 成像过程 CCD 与CMOS 图像传感器光电转换的原理相同,他们最主要的差别在于信号的读出过程不同;由于CCD仅有一个(或少数几个)输出节点统一读出,其信号输出的一致性非常好;而CMOS 芯… 康狮虎发表于工业传感器 固体图像传感器CMOS与CCD的比较 目前,市场上应用的固体图像传感器主要有CCD与CMOS两种。本文从技术性能的...
CCD-RSM优化虎眼万年青 多糖铁复合物的制备工艺 尹玉婷,闫静 * (黑龙江中医药大学,黑龙江哈尔滨150040 ) [摘要]为了探究虎眼万年青多糖铁( Ⅲ )复合物(OPIC)的最佳合成方法,我们采用Plack- ett-Burman设计对虎眼万年青多糖铁复合物制备工艺的主要影响因素进行考察,联用星点设 ...
Efficient adsorption of Crystal Violet Dye using Coir Pith-Derived Biochar: CCD-RSM modelling and Characterization doi:10.1051/e3sconf/202345503002Effective wastewater treatment techniques are needed to mitigate the effects of water contamination, which is a severe environmental issue. The high adsorption ...
In this part, the Response Surface Methodology (RSM) and ANOVA are utilized to estimate the heat transfer rate. The numerical experimental design serves as the foundation for these. 5.1. DOE Experimentation has always been expensive and time-consuming. Therefore, we must do experiments that involve...
All factors affecting the performance of UA-D-μ-SPE-UV–Vis were optimized in detail using CCD of RSM. Under the optimum conditions (eluent solvent: 0.2 mL of methanol, ultrasound extraction time: <10 min, pH of 3.5 and 16 mg of the sorbent), the investigated analyte showed ...

为了探究虎眼万年青多糖铁(Ⅲ)复合物(OPIC)的最佳合成方法,我们采用Plackett-Burman设计对虎眼万年青多糖铁复合物制备工艺的主要影响因素进行考察,联用星点设计(central composite design,CCD)效应面法对显著性因素的水平进行优化,以溶剂加入量,三氯化铁加入量,多糖和柠檬酸钠加入量的比例,温度以及pH值为自变量,以虎眼万...
The CCD-RSM was used successfully as a statistical tool, which reduces the number of trials and optimizes the operating factors. According to the Pareto analysis, the current intensity had a more significant impact on Pb removal efficiency rather than treatment time with contributions of 53.14% ...
一般要先做单因素、然后PB、然后再BBD/CCD吗？他们设计的软件分别有哪些？谢谢！
