Abstract

Calotropis gigantea stems (CGS) has the potential to use as biosorbent for adsorption of Cu(II) ions. In this study, the CGS biosorbent (CGSB) was prepared by drying and grounding. The effect of independent variables on adsorption capacity were investigated. As the result, the maximum adsorption capacity of 53.457 mg/g was obtained the optimal condition which was initial Cu(II) ions concentration of 567.47 mg/L, CGSB size of less than 230 mesh, CGSB mass of 1 g, temperature of 27 oC, pH 5, and contact time of 60 min. The CGSB surface morphology was analysed using SEM. The adsorption of Cu(II) ions fitted well with pseudo first-order adsorption kinetic (PFO-AK) model (R2=0.99), and the PFO-AK adsorption capacity and rate constant obtained were 70.194 mg/g and 0.0877 g/mg.min, respectively. The adsorption isotherm of Cu(II) ions was in accordance with Freundlich model (R2=0.99), and the intensity and volume constants attained were 0.876 and 1.017 L/mg, respectively. This result showed that physical adsorption occurred dominantly than chemical adsorption. The application of CGSB on the wastewater of initial Cu(II) ions concentration of 389.31 mg/L from ex-mine pool of acid mine drainage (AMD) in Jantang village, Lhoong District, Aceh Besar, Aceh Province resulted in adsorption capacity of 37.52 mg/g with adsorption efficiency of 66.13%.

Abstract

Ammonia biosorption by using Enceng Gondok, Eichhornia crassipes, was conducted in outdoor laboratory with objective to study the influence residence time and plant age to ammonia biosorption rate. The research uses reactor test consisting of wet land and sludge. Enceng Gondok is planted on reactor test flown by ammonia as bacth with relatif low enough concentration (2 mg/L), water height 20 cm, plants number in each reactor of 4 stems with variatious plants length 10, 20, 30, and 40 cm, and various residence time 2, 4, 6, and 8 days. Each test conducted was completed by controlling reactor. Research result showed that maximun biosorption occurs at 2 days culturization; ammonia biosorption rate by roots increases as residence time increases. Residence time 2, 4, 6 and 8 days can decrease ammonia concentration up to 1.568 mg/l, 0.245 mg/l, 0.204 mg/l (10%), and 0.022 mg/l, respectively, at plant length 10 cm. Further, research results showed that the more the plants age, the larger the biosorption by plant.Keywords: ammonia biosorption, enceng gondok, plants age, residence time

Abstract

Water quality assessment in the tsunami-affected areas conducted in Meuraxa and Kutaradja sub-districts in the area of Banda Aceh City. Water samples were collected in October 2006 from dug wells of tsunami-affected areas. These were characterized for various physical and chemical parameters. Water quality in the selected areas has shown that the surface water was contaminated due to the tsunami. Total Dissolved Solid, Total Suspended Solid, Acidity, and salinity were high in the affected areas indicating saline water intrusion into surface water tables. Dug wells in the highly affected locations showed higher values of heavy metal ions like Mn, Pb, Cu, Fe, Zn, and Cu compared to the reference points. No ion Hg was found in all samples. Keywords: Banda Aceh, heavy metals, tsunami, water quality
