The dissolving behavior of the S-119 organic filth was studied in different solvents with the oscillator to screen out the better solvent,which is used in the next experiments. The results show that the organic filth has very low solubility in common orga The dissolving behavior of the S-119 organic filth was studied in different solvents with the oscillator to screen out the better solvent, which is used in the next experiments.
