【Abstract】 The changes of iodide ion concentration and pH in iohexol injection with time were measured under 3 000 lx light. The kinetics of light-decomposing reaction for iohexol injection was investigated. The results indicate that light-decomposing reaction for iohexol injection is a first-order reaction. The rate constant of light-decomposing reaction is 1.23×10^-5d^-1.更多还原
