FABRICATION OF A COBALT(II) PVC-MEMBRANE SENSOR BASED ON N-(ANTIPYRIDYNIL)-N'-(2-METHOXYPHENYL)THIOUREA

The N-(Antipyridynil)-N'-(2-methoxyphenyl)thiourea (NTU) was used as an excellent ionophore in the construction of a Co(II) PVC-based membrane sensor. This sensor illustrated very good selectivity and sensitivity towards cobalt ions over a wide variety of cations, including alkali, alkaline ear...
