Abstract

The adsorption process of nitrate from an aqueous solution by using activated Gamalama volcanic ash was investigated. Gamalama volcanic ash (VA) was activated with HNO3 2M. The effect of adsorbent mass and initial nitrate concentration on nitrate adsorption were observed in this study. The adsorption process was conducted using a various mass of adsorbent (1 g, 2 g, 4 g, 6 g, and 8 g), various initial concentrations of nitrate (20 mg/L, 30 mg/L,40 mg/L, 50 mg/L, and 60 mg/L). The increasing of adsorbent mass decreased the adsorption capacity was observed. It was also found that the increase in initial concentration increased the adsorption capacity. The highest nitrate adsorption capacity showed by 1 gram adsorbent for 0.167 mg/g, and at nitrate initial concentration 80 mg/L, for 1.831 mg/g. Adsorption isotherm of nitrate on activated VA was determined and figured. These isotherms were modelled according to Freundlich and Langmuir adsorption isotherm.

Abstract

AbstractGaussian plume model was used to model the SO2 dispersion of 1000 MW coal power plant. This study used two scenarios to figure out the effect of pollutant source physical condition height and diameter of stack to SO2 dispersion which result from coal burning in power plant. The result showed that the increase of sulfur in coal increase ground level concentration of SO2. Decreased of atmospheric stability, caused the increase of SO2 ground level concentration that closer to the pollutant source. Height and diameter of stack, showed similar effect. Sulfur dioxide ground level concentration decrease and occured closer to the pollutant source, caused by  the increase of those parameters. The lowest SO2 ground level concentration resulted from high stack 275 m, with MGLCs 106,55 μg/m3, and diameter 8,75 m; with MGLCs 112,15 μg/m3, which has exceeded the threshold and gave negative effects on human and the environment.Kata Kunci :        Gaussian Plume, Coal power plant, Dispersion model, SO2 concentration

Abstract

Methylene blue is a harmful synthetic dye waste component that poses a significant threat to the environment and human health if not disposed of properly. The best way to tackle this problem is by adsorption through activated carbon from Mulu Bebe banana stems, which are widely available in North Maluku. This agricultural waste can be used to produce activated carbon through pyrolysis at 500ËšC for 30 minutes and activation using 0.5 M KOH solution for 24 hours. The activated carbon is then characterized using FTIR, SEM and XRD, which reveal the presence of various functional groups and pores. The XRD results indicate that the activated carbon structure tends to be amorphous. The adsorption analysis shows that the activated carbon from Mulu Bebe banana stems has a high adsorption capacity of 12.4 mg/g at the optimum condition of pH 7, contact time of 30 minutes, and initial concentration of 50 ppm. The Langmuir and Freundlich equations provide the best fit for the equilibrium adsorption data. By using activated carbon from Mulu Bebe banana stems, we can effectively reduce the amount of methylene blue waste in the environment and protect the ecosystem and human health.
