摘　　要：The standard formation enthalpy of the glycine complex with erbium chloride was determined by using an isoperibolic calorimeter with the hydrochloric acid solution(2 mol/L) as a calorimetric solvent according a proposed thermochemical cycle. The following values were obtained: Δ r H θ m(298.15 K)=-3.331 kJ/mol Δ f H θ m(Er(Gly) 3Cl 3·3H 2O,s,298.15 K)=-3 632.0The standard formation enthalpy of the glycine complex with erbium chloride was determined by using an isoperibolic calorimeter with the hydrochloric acid solution(2 mol/L) as a calorimetric solvent according a proposed thermochemical cycle.
