Determination of polar aromatic amines using newly synthesized sol–gel titanium (IV) butoxide cyanopropyltriethoxysilane

Determination of polar aromatic amines using newly synthesized sol–gel titanium (IV) butoxide cyanopropyltriethoxysilane

A solid phase extraction (SPE) method has been developed using a newly synthesized titanium (IV) butoxide-cyanopropyltriethoxysilane (Ti-CNPrTEOS) sorbent for polar selective extraction of aromatic amines in river water sample. The effect of different parameters on the extraction recovery was studie...
