Abstract
The forward dissolution rate of a borosilicate waste glass was determined as an interlaboratory study(ILS) testing program for the evaluation of precision in the measurement of the dissolution rate or a waste glass using a single-pass flow-through(SPFT) test, whose conducting practice has been written for standardization through American Society for Testing and Materials (ASTM). A simulated low-activity waste glass powder with a size of 100/200 mesh was dissolved by lithium buffer solution (pH=10) at 70? under Ar atmosphere. By plotting the dissolution rates as a function of silicon and boron concentration in eluate, the forward dissolution rate of the glass was obtained as about
Single-pass flow-through (SPFW) 방법에 의한 유리고화체의 용해율 측정에서 정밀도를 구하기 위하여 연구소간 실험프로그램의 하나로서 붕규산유리고화체의 정용해율을 구하였는데, 이 SPFT 방법은 American Society for Testing and Materials (ASTM)에서 표준화를 위하여 작성되었다. 이를 위해 100/200 mesh 크기의 모의 저방사능 유리고화체 분말시료를
