Thismethod does not purport to address to all of the safety problems associated with its use, but it is theresponsibility of the user to search and establish appropriate safety and health practices and determinethe applicabi
22、lity of regulatory limitations prior to use.2 PrincipleThe vegetable oil methyl ester sample is diluted with a xylene solution.The sodium content in the sample is directly determined by flame atomic absorption spectrometry at thewavelength of 589 nm. The calibration solutions used are prepared from
23、a sodium organometallic salt dissolved ina mixture of xylene and stock oil. The addition of stock oil to the calibration solutions is necessary in order toimprove their storage (the low element contents are unstable) and the linearity of the calibration.WARNING The ester sample shall be diluted at l
24、east 25 times with xylene so that the comparison of themeasurements of the sample solution and standards is valid.NOTE Xylene can be replaced by cyclohexane or light petroleum in those laboratories that are not authorized to usearomatic solvents.3 ReagentsUse only reagents of recognised analytical g
