| 中文摘要: |
| 用微波消解-电感耦合等离子体发射光谱法（ICP-OES）检测异戊橡胶（IR）中钛质量分数。结果表明，消解体 系为硝酸/硫酸/双氧水（体积比为5/1/1），谱线波长为334.940 nm，ICP-OES仪射频功率为1 300 W、雾化气流量为0.55 mL·min-1、进样量为1.5 mL·min-1、等离子气体流量为10 L·min-1时，检测的IR钛质量分数相对标准偏差为1.07%，加 标回收率为95％～105％。该检测方法快速、准确、灵敏度高，满足IR中钛质量分数的检测要求。 |
| 英文摘要: |
| Titanium content in isoprene rubber（IR）was determined by microwave digestion- inductively coupled plasma-optical emission spectrometry（ICP-OES）. When the digestion system was nitric acid/sulfuric acid/hydrogen peroxide with the volume ratio of 5/1/1，the spectral wavelength was 334. 940 nm，RF power of ICP-OES was 1 300 W，atomization flow was 0. 55 mL·min-1，injection volume ass 1. 5 mL·min-1， and the plasma flow rate ass 10 L·min-1，the relative standard deviation of measured IR titanium content was 1. 07%，and the recoveries were 95%～105%. This detection method was fast，accurate and sensitive， and met the testing requirement of determining titanium content in IR. |
