Removal of rhodamine 6g and crystal violet dyes from water sample using cellulose acetate-(3-aminopropyl)- triethoxysilane sorbent
In this work, cellulose acetate-(3-aminopropyl)triethoxysilane (CA-APTES) was evaluated for the first time as adsorbent for the removal of rhodamine 6G (R6G) and crystal violet (CV) in water. The sorbent was first synthesized then characterized using attenuated total reflection-Fourier transform inf...
