| Abstract |
In this research, natural and intact hair is used and experiments are performed within pH range from 1 to 12. Given that nitrogen oxide is the major cause of acid rain, nitric acid was used for making acidic solution and for the basic one, normal potassium hydroxide was used. Hair was paraffin-embedded and microtome was used to get the cross-section. In each pH, IR spectrums and cross-section images are obtained with FT-IR microspectroscopy and surface images with SEM. Since a hair fiber can be divided into outer layer(cuticle) and inner part(cortex), comparisons between these two parts are also made in each part. Especially in IR analysis, Amide I band was used for studying secondary structures of protein. From the controlled experiments, we will present how the human hairs can be affected and the detailed analysis in each pH condition will be presented. |
