Method for measuring bis(2,4,4-trimethylpentyl) phosphinic acid concentration by ICP-OES |
| abstract |
Provided is a method for measuring the concentration of bis(2,4,4-trimethylpentyl) phosphinic acid using ICP-OES, the method including the steps of: (a) decomposing and dissolving an organic solvent into an acid; (b) preparing a phosphorus reference solution and producing a calibration curve using the phosphorus reference solution; and (c) measuring the phosphorus concentration (mg/L) of the solution of step (a) using the calibration curve of step (b) and calculating the concentration (v/v %) of bis(2,4,4-trimethylpentyl) phosphinic acid in the organic solvent using the phosphorus concentration. |
