    Abstract: A method of analyzing an antimony ion of an embodiment, the method includes using a first analysis solution or a second analysis solution, the first analysis solution containing trivalent antimony ions and pentavalent antimony ions, the second analysis solution being a solution obtained by mixing a first acid and the first analysis solution, and mixing the first analysis solution or the second analysis solution with a second acid to obtain a third analysis solution in which the pentavalent antimony ions are chlorinated and which contains [SbCl6]− ions, mixing the third analysis solution and a first organic solvent and phase-separating the mixture into a fourth analysis solution as an organic phase and an aqueous phase to obtain the fourth analysis solution, mixing the fourth analysis solution and a coloring liquid containing rhodamine B to obtain a fifth analysis solution, and evaluating a concentration of the pentavalent antimony ions in the first analysis solution from color of the fifth analysis solution. A total concentration of nitric acid, cerium (IV) nitrate, and cerium (IV) sulfate contained in the first analysis solution is 0.00 mol/L or more and 0.1 mol/L or less. The total concentration of nitric acid, cerium (IV) nitrate, and cerium (IV) sulfate contained in the first acid is 0.00 mol/L or more and 0.1 mol/L or less. The total concentration of nitric acid, cerium (IV) nitrate, and cerium (IV) sulfate contained in the second acid is 0.00 mol/L or more and 0.1 mol/L or less.

    Abstract: A molecular detection apparatus according to an embodiment includes: a distributor which ionizes a target containing substances to be detected, applies voltage to ionized substances, and extracts the substances to be detected according to a time-of-flight based on the speed; a detector which detects the substance to be detected dropped from the distributor; and a discriminator which discriminates the substance to be detected. The detector includes: a plurality of detection units including field effect transistors using graphene layers; and a plurality of organic probes which are provided on the graphene layers, and at least some of which have different bond strengths with the substances to be detected. The substance to be detected is discriminated depending on a signal pattern based on intensity differences of the detection signals generated by differences in the bond strengths between the organic probes and the substances to be detected.
