【摘要】 安宁及其制剂和泛酸钙,经降解成相应的铵盐,两者于浓碱存在下均逸出 NH₃,可用氨气敏电极测定。在1×10^-4～1×10^-2mol/L 浓度范围内,校正曲线呈线性,所测得结果与凯氏定氮法基本一致。更多还原

【Abstract】 Meprobamate and its preparations as well as calcium pantothe-nate were decomposed to form the corresponding ammonium salts.The ammoniaevolved at pH>11 from the above solutions could be determined directly usingan ammonium gas-sensing electrode.The calibration curves showed the linearityin the range of 1×10^-4～1×10^-2 mol/L.The results obtained were comparable tothose by Kjeldahl method.更多还原
