The photocatalytic degradation of the commercial reactive Black5 (RB5), Blue19 (RB19), Green19 (RG19), Red120 (RR120), and Yellow81 (RY81) in aqueous solution and sunlight were examined in the presence of Fe2O3 and the mixture Fe2O3/H2O2 as catalysts. The results showed that the photocatalytic degradation followed first-order...

Color and organic matter removal from dyehouse effluent remains a challenging issue for the environmentalist textile dyer. Until now, various treatment processes have been proposed with limited success. In this study, dye model industrial pollutant Reactive Black 5 (RB5; 20 mg/L) could be rapidly degraded by persulfate (PS)-enhanced photocatalytic using novel, home-made lanthanum iron oxide (LF...

PT. Kurnia Batang Hari is a palm oil processing factory into oil. At PT KBHB there tool called “Steam Turbine Generator Type RB5” which functions as power generator. This study aims to determine the effect of load on mass flow rate, turbine generator power, and efficiency steam The research method take boiler data directly for 1 week. Get enthalpy value from table can calculate based objective....

Electrochemical-oxidation of Reactive Black-5 (RB5) was conducted for degradation using DSA type Ti/RuO2-SnO2Sb2O5 electrode. In the study, for electro-oxidation, electrode was indigenously fabricated in laboratory using titanium as substrate. This substrate was coated using different metal oxides RuO2, Sb2O5 and SnO2 by thermal decomposition method. Laboratory scale batch reactor was used for ...

In this study, the effect of preparation route of magnetic graphene oxide (mGO) on Reactive Black 5 (RB5) adsorption was investigated. The synthesis of mGO was achieved both with (i) impregnation method (mGOi nanoparticles), and (ii) co-precipitation (mGOp nanoparticles). After synthesis, the full characterization with various techniques (SEM, FTIR, XRD, DTA, DTG, VSM) was achieved revealing ma...
