摘要:
通过实验认为钼蓝分光光度法适合于生物柴油中微量磷含量的测定。优化了实验条件, 用直接定容取代定容后再分取, 使样品的用量减少至原来的1/ 5 , 样品炭化和灰化等处理时间大大缩短, 使整个分析时间缩短约1.5 h。用KOH 为催化剂, 以 大豆油、菜籽油、棉籽油、玉米油、花生油和麻油为原料合成了6 种生物柴油。用钼蓝分光光度法测定了它们的磷含量, 结果 表明当6 种植物油采用碱催化制成生物柴油后磷含量显著降低, 都小于5 mg/ kg , 能满足德国生物柴油中磷含量小于10 mg/ kg 的标准要求。
Abstract:
It has been proved that the phospho - molybdenumblue photomet ry can be applied for the determina2 tion of phosphorus in biodiesel fuels with satisfactory result s. The determinating conditions were optimized. In the new analytical method , the sample size is only 1/ 5 of the previous one. The sample handling time such as carbonization and ashing was shortened greatly. So the analysis time was shortened about 115 h. The pure biodiesel fuels of six edible plant oils , which are rapeseed oil , peanut oil , corn oil , cottonseed oil , sesame oil and soyabean oil , have been made by means of base catalysis and t ransesterification. The phosphorus content in 6 biodiesel fuels , all less than 5 mg/ kg , has been determinated by phospho - molybdenumblue photomet ry , ac2 cords with the specification of Germany biodiesel fuel and is much lower than that in it s plant oil when the biodiesel fuel was made f rom it s plant oil by base catalysis.
