In the tungsten industry as light source material, tungsten filament, which was used as light source material, could form after molybdenum wire, which was used as the center supporter for coil hape tungsten wire. was removed. The purpose of this study is to develop a new process named "hydrogen peroxide dissolution method". This process uses hydrogen peroxide. which is harmless to human body and oxidizes molybdenum wire selectively. The advantages of the hydrogen peroxide dissolution method were no discharge of noxious matter when dissolution of molybdenum wire which was used as the center supporter, easy reactions in room temperature complete recovery of dissolved molybdenum. This study aimed at gathering the basic data of molybdenum wire dissolution-recovery process and proposing the reaction condition of molybdenum wire dissolution-recovery process and the factors influencing those reactions. This process uses advanced oxidation processes, for the quantity of hydrogen peroxide decrease The results were as follows: 1.An incandescent electric lamp type: FL type: A standard of commodity (P.W.: 19± 1.0㎎, C.R.: 4.5±0.3Ω) 1) Only hydrogen peroxide treated: Reaction Time: 65Min., P.W.: 18.60㎎. C.R.: 4.60Ω 2) Advanced oxidation processes (70% of H₂O₂): Reaction Time: 64Min., P.W.: 18.61㎎, C.R.: 4.61Ω 2. A Fluorescent lamp type: GLS type: A standard of commodity (P.W.: 11.8±0.2㎎. C.R.: 65±1.5Ω) 1) Only hydrogen peroxide treated: Reaction Time: 72Min.. P.W.: 11.88㎎, C.R.: 65.62Ω 2) Advanced oxidation processes (70% of H₂O₂):: Reaction Time: 71Min.. P.W.: 11.88 ㎎. C.R.: 65.63Ω
