description A method for determining rare earth gadolinium ion concentration in a solution relates to the technical field of detection on ion concentration. The method comprises firstly establishing a standard curve conversion equation of the transverse relaxation rate 1/T[2] of hydrogen proton in a Gd concentration solution and the Gd concentration; then employing a CPMG sequence for scanning, and determining the transverse relaxation rate 1/T[2] of hydrogen proton in a to-be-determined sample solution; and then substituting the transverse relaxation rate 1/T[2] of hydrogen proton in the to-be-determined sample solution into the established standard curve conversion equation of the transverse relaxation rate 1/T[2] of hydrogen proton in the Gd concentration solution and the Gd concentration, calculating to obtain the rare earth gadolinium ion concentration in the to-be-determined sample solution. The method is simple to operate and high in accuracy, and is capable of realizing rapid determination and quantitative analysis.
