(FTIR) was used to study the chemical structure of chars obtained from corn straw stalk ,cotton stalk ,pine sawdust and rice husk in the range from 300℃ to 600 ℃ .Experimental results showed that as the temperature increased , functional groups [ - OH ] , [ - CH ] , [ - CO - ...
functional groups in an organic molecule. Functional groups have vibration frequencies that are characteristic of that functional group. These vibration frequencies fall with the infrared (IR) frequency range. As such, passing an IR signal through the organic compound causes the functional groups to ...
