  Author(s): Kwang-Sun KangKwang-Sun Kang
  
  Minimizing or avoiding the creation of waste solvents can be most effective in protecting environment and managing the cost. Since fabrication of silica spheres (approximately 1.0 g of silica spheres with diameter of approximately 300 nm) for photonic crystal requires relatively large amount of solvents (100 ml 2-propanol and 100 ml NH4OH solution), it will be ideal to use recycled solvents for reducing waste solvents. Monodisperse silica spheres were synthesized with Stöber synthetic process. The diameter of the spheres was uniform when the ratio of 2-propanol and NH4OH was 1:1. To investigate the effect of recycled solvents, the ratio of 2-propanol:NH4OH maintained 1:1. The spheres were separated by filtration or centrifuge. The mixture of solvents was recycled repeatedly after separating the spheres. The spheres became irregular shape when the mixture of solvents recycled by f.. View More»
