| 1 | The result indicates that the main uncertainty is from the titer of sodium hyposulfite standard solution. | |
| 2 | Now know that the stabilizer can be divided into five categories: thiourea, sodium thiosulfate and other sulfur compounds; | |
| 3 | After comparison, sodium hyposulfite is the preferred absorbent, which the resultant has no influence on the environment with sodium hyposulfite over absorbed dose. | |
| 4 | Laboratory studies have shown that sodium sulfide or the sodium hyposulfite can be oxidized to elemental sulfur by strain 1 or strain 2, they can obtain energy from the oxidation. | |
| 5 | OBJECTIVE: To improve the formula of sodium thiosulfate paint so as to make it more adaptable to the clinical needs. |
