| Abstract: | A spectrophotometric method for determination of fluorescein sodium tracer in drilling fluids was studied in this paper. In the sodium acetate buffer media with pH〉9.0, the detection limit of 0.005μg/mL for fluorescein sodium tracer was achieved under the optimal conditions, where λ is 485 nm and the length of colorimetrie utensil is 5 era. The relative standard deviation （RSD） is 8.7%, which was obtained by determination of 10 simulated fluorescein sodium samples with concentration of 0.012μg/mL. The method can satisfy the requirements for tracing drilling liquid. |
