Photocatalytic degradation of organic waste derived from textile dye by ZnO-Ag nanocomposite synthesized by spray pyrolysis Open
Organic waste derived from the textile dye of textile industry in Gresik is toxic and dangerous to humans and the ecosystem. The waste from textile dye must be handled properly before its disposal to the river. Photodegradation of the orga…
Characterizations of Ag doped ZnO particles via flame pyrolysis method for degradation of methylene blue Open
Flame pyrolysis is widely used for the fabrication of particles because of great crystallinity and fine size distribution of the products. In this research, ZnO-Ag particle materials have been favourably made by flame pyrolysis. The impact…
Effect of Light Intensity, CO<sub>2</sub> Gas Concentration, Culturing Period and Walne Nutrient Concentrations on Biomass and Lipid Productivity of <i>Chlorella vulgaris</i> in Sea Water Media Open
The biomass and lipid productivity of Chlorella vulgaris cultured in sea water media were conducted in this study. The effect of light intensity (5000 and 10000 lux), CO 2 gas concentration (0.03%, 1% and 2%), culturing period (7 and 17 da…
