Chemical liquid purification method and chemical liquid

A chemical liquid comprising:

• an organic solvent;
• a stabilizer;
• at least one kind of metal ions selected from the group consisting of Fe, Cr, Pb, and Ni, and
• at least one kind of metal particles selected from the group consisting of Fe, Cr, Pb, and Ni,
• wherein the organic solvent is at least one kind of compound selected from a group consisting of propylene glycol monomethyl ether, propylene glycol monoethyl ether, propylene glycol monopropyl ether, propylene glycol monomethyl ether acetate, ethyl lactate, methyl methoxypropionate, cyclopentanone, cyclohexanone, γ-butyrolactone, diisoamyl ether, butyl acetate, isoamyl acetate, isopropanol, 4-methyl-2-pentanol, dimethylsulfoxide, N-methyl-2-pyrrolidone, diethylene glycol, ethylene glycol, dipropylene glycol, propylene glycol, ethylene carbonate, propylene carbonate, sulfolane, cycloheptanone, and 2-heptanone,
• in a case where the chemical liquid contains one kind of the at least one kind of metal ions, a content of the at least one kind of metal ions with respect to the total mass of the chemical liquid is equal to or smaller than 100 mass ppt,
• in a case where the chemical liquid contains two or more kinds of the at least one kind of the metal ions, a content of each of the at least one kind of metal ions with respect to the total mass of the chemical liquid is equal to or smaller than 100 mass ppt,
• in a case where the chemical liquid contains one kind of the at least one kind of metal particles, a content of the at least one kind of metal particles with respect to the total mass of the chemical liquid is equal to or smaller than 100 mass ppt, and
• in a case where the chemical liquid contains two or more kinds of the at least one kind of metal particles, a content of each of the at least one kind of metal particles with respect to the total mass of the chemical liquid is equal to or smaller than 100 mass ppt.
