Abstract The corrosion behavior of zinc in ammonium chloride solution with thiosemicarbazido(TSC) was studied by means of corrosion potential measurement,electrochemical impedence spectroscopy and weightloss method.The experimental results showed that TSC had remarkable inhibition effect on the corrosion of zinc in 26% ammonium chloride solution.The inhibition efficiency of the TSC increased with the increase in its concentration up to 0.2g·L-1.The inhibition of TSC for zinc was found to be the geometric blocking effect,and its adsorption isstherm approximately followed Langmuir isotherm equation.
