Electroanalytical and naked eye determination of Cu2+ ion in various environmental samples using 5-amino-1,3,4-thiadiazole-2-thiol based Schiff bases

Polyacrylonitrile-based fiber modified with thiosemicarbazide by microwave irradiation and its adsorption behavior for Cd(II) and Pb(II)

“…Compared with the reported fibrous adsorbents in Table 6 which were prepared through conventional heating, the adsorption capacities of PANMW-TSC fibers for these two metal ions were higher, and the duration of functionalization process decreased incredibly by using MW irradiation. The consumed time declined from 5-29 h to 0.5 h with higher grafting rate of N and S atoms onto the fibers which both took effects in the adsorption process [41,42].…”

Recent Advances in Chemical Sensors for Soil Analysis: A Review

“…A 1-phenyl-2-(2-hydroxyphenylhydrazo)butane-1,3-dione (H 2 L) ionophore-based copper-selective PVC membrane electrode for precise copper analysis in soils polluted by oil was developed by Kopylovich et al [170]. Singh [171]; two polydentate Schiff bases, 4-(5-mercapto-1,3,4-thiadiazol-2-ylimino)pentan-2-one (S 1 ) and (2-(indol-3-yl)vinyl)-1,3,4-thiadiazole-2-thiol (S 2 ) [172]; and ionophores inside PVS-based solvent polymeric membranes for selective detection of Cu 2+ ions. Optimization of membrane composition, working conditions, and transducer material (classical inner liquid contact sensors vs. coated graphite electrodes, CGE, and coated pyrolytic graphite electrodes, CPGE) was performed.…”
