Control of leachable mercury in fluorescent lamps by gelatin

   
   

The formation of leachable mercury upon disposal in a landfill or during TCLP testing of mercury vapor discharge lamps is substantially prevented by incorporation of an amount of gelatin or a degradation product of gelatin which is effective to substantially prevent formation of ferric and cuprous compounds responsible for forming leachable mercury compounds.

La formación del mercurio leachable sobre la disposición en un terraplén o durante la prueba de TCLP de las lámparas de descarga del vapor del mercurio es prevenida substancialmente por la incorporación de una cantidad de gelatina o un producto de la degradación de la gelatina que es eficaz prevenir substancialmente formación de los compuestos férricos y cuprosos responsables de formar el mercurio leachable compone.
