| Abstract: |
| To investigate the lead release from rubber tubes. Methods The lead content in 3 types of rubber tubes were determined, and the Pb release were analyzed from the rubber tubes under different immersion time and temperature conditions(22,40,60,80,100℃) in tap water. Results The lead content of rubber tubes 3#, 1#, and 2# decreased successively, and the amount of Pb release also decreased successively under the same conditions; The amount of Pb release showed a downward trend with the number of the immersion time increases. As the temperature increased, the amount of Pb release is increasing, and the release rate is also increasing. Conclusion The Pb release of rubber tubes with high lead content is also higher. Pb release decrease gradually as the increasing of the number of immersion time, and it increases with the increase of immersion temperature. |
