Sulfonamides and their derivatives are being used as potent chemosensors for various ions. Sensing ability of 4-methyl-N-(pyridin-2-yl) benzene-1-sulfonamide (S) was tested towards different cations i.e. Zn 2+ , Fe 2+ , Pb 2+ , Ni 2+ , Sr 2+ , Cd 2+ , Cu 2+ , Co 2+ , Hg 2+ and Al 3+ in Dimethyl Sulf...
