Linear type SFL (spent fluorescent lamp) can be classified by 3-banded lamp and general lamp. Linear type SFL is separated by the end-cutting technique to examine the distribution of mercury in the major components such as base cap, glass part and phosphor powder. In this study, the concentration of mercury is analyzed by DMA (Direct Mercury Analysis) method for major components in linear type SFL. From the results of mercury distribution for 3 companies, the concentration of mercury in 3-banded lamp is less than that in general lamp. And phosphor powder has greater than 80% of total mercury amount in SFL and the mercury concentration in phosphor powder is measured between 1,250 ppm and 1,740 ppm. The mercury concentration in phosphor powder can be changed by the type of lamp, company, and period of usage. KET and TCLP are carried out for phosphor powder, glass, and base cap to estimate the hazardous characteristic. From the results of KET and TCLP test for general lamp and 3-banded lamp, phosphor powder from general lamp and 3-banded lamp should be controlled separately by stabilization or other methods to reuse as a renewable material because the phosphor powder is determined as a hazardous waste.
