Foreword

Chapter 4 of this standard are mandatory, others are recommended. This standard with the FAO and the World Health Organization FAO/WHOJECFA (1995) and JECFA (2002) "food-grade white The degree of identity oil "(English) is non-equivalent. (2002) The main difference between this standard and FAO/WHOJECFA (1995) and JECFA as follows. --- the FAO/WHO standard oil grades. in the low viscosity Ⅰ, Ⅱ, Ⅲ grade white oil and a high viscosity to low viscosity in No. 2, No. 3, No. 4 and No. 5 high viscosity, low viscosity while increasing the number 1; --- increase the technical requirements of color; --- increases as the kinematic viscosity 40 ℃ report value; --- abolished the upper limit of molecular weight; --- This standard quality indicators are used all existing national standards or industry standards of measurement. This standard replaces GB 4853-1994 "food grade white oil." The main difference compared with the present standard GB 4853-1994 as follows. --- The oil grades in GB 4853-1994. No. 10, No. 15, No. 26 and No. 36 to low, medium viscosity No. 1, No. 2, No. 3, No. 4 and No. 5 high viscosity; --- deg.] C kinematic viscosity increase 100; --- increased "initial boiling point", "5% (mass fraction) carbon atoms distillation point", "5% (mass fraction) distillation point temperature", "Average Molecular Quality "of technical requirements; --- canceled "flash point (open)", "mechanical impurities" and "water" technical requirements. Appendix A of this standard is normative. The standard proposed by China Petroleum and Chemical Corporation. This standard by the Chinese Research Institute of Chemical Technology, Fushun Petrochemical Corporation oil. Drafted by. China Petroleum & Chemical Corporation Fushun Petrochemical Research Institute. The main drafters. Wang Lihua, Wang Lijun. This standard supersedes the previous editions are. --- GB 4853-1984, GB 4853-1994. Food grade white oil Range 1 This standard specifies the technical requirements of food grade white oil, test methods, marking, packaging, storage, delivery and acceptance sampling.

If necessary, the solution was taken at 20 ℃ 10mL in 500mL volumetric flask and water was added to the reticle. A. 4.2 was prepared calibration curve In a series 100mL volumetric flask, added with a pipette 0mL respectively, 1mL, 2mL, 3mL, 4mL, 5mL lead standard solution And diluted to about 50mL. And 10mL of concentrated sulfuric acid was added 8mL of concentrated hydrochloric acid, shake to dissolve. Complete dissolution, diluted with deionized water To the groove. The solution contained in each series 0μg/mL, 0.2μg/mL, 0.4μg/mL, 0.6μg/mL, 0.8μg/mL and 1.0μg/mL Lead. A. 4.3 to prepare a sample solution In a 100mL ~ 150mL Kjeldahl flasks 2.5g accurately weighed sample (weighing accuracy 0.1mg), was added 5mL dilute nitric acid. When a slow initial reaction, heat slowly, vigorous reaction stopped until further and then cooled. 4mL of concentrated sulfuric acid was gradually added (control Process a rate system, so that no excessive heating of the foam, generally requires 5min ~ 10min), heating is started until the liquid color Book GB 4853-2008 Significantly darker, that began to darken. Graded was slowly added concentrated sulfuric acid was heated between every two added until the black again. Do not violently heated Induced to excessive darkening. Throughout the process, there should be a small amount of free nitric acid. This process continues until the solution became pale yellow and In the subsequent heating process is no longer darker color. If the solution is still discolored and a small amount of perchloric acid solution and 0.5mL of concentrated nitric acid was added Heat about 15min, then a solution of perchloric acid was added 0.5mL, then heated for several minutes. Recording the total amount of concentrated nitric acid is used. Cool slightly and use 10mL of deionized water. The color of the solution should be completely colorless (if there is a lot of iron, probably as a pale yellow solution). Steady cook Boiling, to avoid bumping until white smoke appears. To cool, then add 5mL of water to boil again appear smooth smoke. Finally, cooling, 10mL5mol/L hydrochloric acid was boiled for a few minutes smoothly. The cooled solution was transferred to a 50mL volumetric flask single line minute, rinsed with a small amount of water Kjeldahl flask. Kjeldahl flask rinsing water was added to the flask, diluted with water to the reticle. The solution is called solution A. Preparing a reagent blank with the same amount of reagent (oxidized sample during the reagents used). A. Test Procedure 5 A. 5.1 instrument conditions Analysis ray wavelength. 283.3nm. Other Conditions vary depending on the instrument model, the recommended various instrument parameters are different. And when using certain parameters to be optimized, To get the best results. Accordingly, reference should be made to adjust the instrument and the flame type specified above is provided in the manufacturer's instructions. A. Step 5.2 The atomic absorption spectrophotometer operating condition setting in the selected state, a suction concentration of the element containing the highest standard solution of the test, Optimization of settings and conditions of the instrument, so that the recording paper reaches the maximum, or full scale offset value. Absorption values for other standard solution, rendering Net absorption element concentration value curve and the relationship between the standard solution. The inhalation solution A was dissolved by the sample or samples obtained by wet oxidation and the corresponding The blank solution, the net absorbance detection. The upper curve drawn using the measured concentration of the sample solution measured elements.
