摘要：
The present invention provides a quantitative analysis method of sodium carboxymethylcellulose in a preparation, which comprises: a step of putting a test liquid and a standard solution in a glass-capped testing tube at a certain volume ratio to a separately prepared reaction solution, mixing them, treating the mixture immediately at 90-105°C for two hours, and cooling the mixture a step of measuring absorbance of the test liquid and the reaction solution, which are treated as above and a step of putting the measured absorbance in a formula and deducting the content ratio to the indicated quantity of sodium carboxymethylcellulose in the preparation. The present invention provides a quality assurance (QA) method of a preparation including sodium carboxymethylcellulose, which comprises: a step of determining the content ratio to the indicated quantity of sodium carboxymethylcellulose in the preparation in accordance with the quantitative analysis method and a step of comparing the determined content ratio with a standard value and determining the quality of the preparation. The present invention provides a quantitative analysis method of sodium carboxymethylcellulose, which comprises: a step of preparing a plurality of standard solutions of sodium carboxymethylcellulose of a known concentration, which is selected from a certain range a step of drawing a calibration curve from the measured absorbance for the plurality of standard solutions in a specific wavelength and deducting a linear equation of absorbance in accordance with concentration and a step of putting the absorbance of the test liquid, which is measured in the same wavelength as that for the standard solutions, in the deducted equation, calculating the corresponding concentration value, and determining the concentration value as the concentration of sodium carboxymethylcellulose of the test liquid.COPYRIGHT KIPO 2017본 발명은 유리마개 시험관에 검액 및 표준액을 별도로 준비한 반응 용액과 일정한 부피비로 투입하여 혼합하고, 즉시 90 내지 105℃에서 2시간 동안 처리한 후
