Abstract

Determination of optimum pH and contact time, of broken brick from Latuhalat village as adsorbent of Pb2+ through impregnation with di-(2-ethylhexcyl) phosphate acid (D2EHPA) has been done. Bricks impregnated with di-(2-ethylhexcyl) phosphate acid concentration of 700 ppm to enlarge the surface area of ??adsorption on bricks. The result of analysis using AAS show that optimum contact time is 3 hours, optimum pH is 8, with weight of adsorbent is 0,2 g, adsorbate concentration is 100 ppm and adsorption capacity is 49,9985 mg/g adsorbent.

Abstract

Characterization of Myristicin isolated from nutmeg oil has been done. The study was started by isolating the nutmeg oil from the nutmeg using steam distillation for 8 hours, yield 2.40% of nutmeg oil. The isolation of myristicin from nutmeg oil by fractional distillation under reduced pressure, yield 8.02% of myristicin with 100% of purity. The purity was determinated using GC and the structure elucidation was analyzed by FTIR, 1H-NMR, and MS spectromecters
