A portable luminescence spectrofluorometer weighing only 1.5 kg that uses multiple light emitting diodes (LEDs) as excitation sources was developed and evaluated. Excitation using a sequence of seven individual broad-band LED emission sources enabled the generation of excitation-emission spectra using a light weight (<1.5 kg) spectrometer. Limits of detection for rhodamine 6G, rhodamine B, and ...
Humic acid (HA) modifying Fe(3)O(4) nanoparticles (Fe(3)O(4)/HA) was developed for removal of Rhodamine B from water. Fe(3)O(4)/HA was prepared by a coprecipitation procedure with cheap and environmentally friendly iron salts and HA. TEM images revealed the Fe(3)O(4)/HA (with ≈ 10 nm Fe(3)O(4) cores) were aggregated as aqueous suspensions. With a saturation magnetization of 61.2 emu/g, the Fe(3...
White cement-based mortars in urban areas are usually discolored and altered their esthetic properties due to air pollutants. The addition of nanoparticles these can provide photocatalytic that decompose pollution agents. Likewise, other hydrophobic agents have been individually studied improve outdoor building constructions. Therefore, this study presented the effect adding nano-TiO2 silicone ...
Global environmental pollution challenges can be alleviated if proper disposal and conversion of wastes is promoted. An attempt of converting waste to wealth was made in this study by converting oil palm empty fruits bunch to activated carbon through chemical activation with potassium hydroxide which was used for adsorption of Rhodamine B dye from waste water. Fixed-bed column adsorption system...
