Using highly pure graphite rod and B4C/graphite composite rod as electrods, some macroscopic amounts of boron-doped fullerenes, such as C60-nBn and C70-nBn (n=1,2,3) are syn-thesized by DC arc burning method and extracted by o-xylene from the soots under nitrogen for the first time. The boron-doped fullerenes are characterized by FDMS.
Triethyl Phosphite is the intermediate of producing nervous toxin of organic phosphate,which is involved in the chemicals of schedule 3. in Convention On The Prohibition Of The Development,Production,Stockpiling And Use Of Chemical Weapons And On Their Destruction.A method for the determination of triethyl phosphate was established by GC-MS/SIM.Average recovery was 96.3%-111.5% with linear range between concentration and peak area varying from 0.546-10.928 mg/L and the detection limits were 0.011 ng.
