为了定性和定量分析煤沥青萃取物样品的官能团精细结构信息,使用Peak Fit v4.12软件分别对萃取物样品红外光谱特征范围内的吸收峰进行了分峰拟合处理。 2结果与讨论 2.1红外光谱分析 2.1.1FTIR光谱峰归属 如图1所示为AGMP萃取物各样品的FTIR谱图,不同萃取物样品的红外光谱具有相似的吸收峰和特征吸收峰。根据文献[7-8...
The results showed that the maximum weight loss peak temperature(Tm ) was 347. 8 ℃, and the residual was 32. 0%, CO2 was the main gas product under the N2 atmosphere. The solid residual was only 6. 5%, and Tm was 282. 1 ℃, and the released gas wer...
工具栏 （7）此处为增删峰界面，可点击删除影响峰，点击Next。如：HA在1637cm-1位置有H2O特征峰，为避免其影响计算明胶的各二级结构，可在此处删除H2O的特征峰。（7）此处为图线拟合界面，选择峰对其逐个拟合，直到右方“红色”拟合线与“黑色”原曲线基本重合为止，点击Next。选择第几个峰 ...

•Automatic atmospheric suppression: check to have software remove any lines from residual H2O and CO2. •File Handling: leave 'Save automatically' deselected and 'Save interferograms' selected. This way you will only save the files you choose to save. By saving the interferogram you will have...
(6)Cr (OH)3 (Trivalent Cr) + 5OH- + 3Fe3+ ⇄ CrO42- (Hexavalent Cr) + 4H2O + 3Fe2+ To avoid these redox reactions during the analysis of Cr(VI) new methods to analyse Cr(VI) in welding fumes are being sought after and continually explored. An interesting possibility is the ...
气氛补偿功能可以消除比率光谱图中H2O/CO2的干扰。 要进行气氛补偿的图谱文件,除了吸收(或透射)数据块外,还应包含Single Channel Sample Block和Single Channel Background Block(测试前应在Measure-Advanced Measurement中,力口选Single Channel和Background这一项数据块加以保存)。 选择Manipulate—Atomspheric Compensation...
The mineral composition and mineral transformation of coal ash were investagated by FTIR.It is shown that,as the ashing temperature go up,the water peak at wavenumber 3452cm-1,1640 cm-1 disappears gradually,the mullite derived from kaolinite was formed at peak wavenumber 1100 cm-1,695 cm-1,...
As O2 concentration increases profiles shift through lower temperature zone, peak and burnout temperatures decrease, weight loss rate increases and complete combustion is achieved at lower temperatures and shorter times. During pyrolysis and combustion tests gaseous products CO2, CO, H2O, CH4, SO2 and...
