dc.description.abstract	The lead (Pb) content in the Refind Glyserin that was produced by PT. Ecogreen Oleochemical Medan as analyzed using Spectrofotometric method at the wavelength λmax = 480 nm used thioacetamide concentrated and acetat buffer as a colouring reagent. The result of analysis showed the lead concentration in Refind Glyserin sample A-015P = 1,65 ppm, sample A-016P = 1,108 ppm, sample A-021P = 1,664 ppm, sample A-020P = 1,107 ppm, and sample A- 052 = 1,099 ppm. Refind Glyserin which produced by PT. Ecogreen Oleochemical Medan was still under from the standart undertaking which is max 5 ppm.	en_US
