Application of andesite and hydrolyzed poly acrylonitrile andesite composite for adsorption of Al(III), Fe(III), CH3SH, and H2S form aqueous solutions

Characterization

Fourier transform infrared (FTIR)

An FTIR spectrophotometer was used to evaluate andesite and HPAA composite before and following the metal ions adsorption (Al(III), Fe(III)) and molecules (H₂S, CH₃SH). The FTIR analysis displayed…
