Abstract

The preparation of polyelectrolyte complex (PEC) as supporting material of urease immobilisation for  Hg(II) biosensor has done. PEC membrane can be prepared by mixing hydrosol alginate and chitosan hydrosol with 1: 1 ratio at pH of 5.28 approximately. The optimum conditions and characteristics of biosensor was determined. The formed alginate–chitosan PEC membrane was confirmed by using FTIR spectroscopy and SEM analysis. The results shoed that PEC of alginate-chitosan was formed and the proposed biosensor is an excellent platform for sensitive detection of Hg (II).

Abstract

This study deals with the isolation and characterization of humic acids from Batujai Dam subgrade, Central Lombok. Humic acid isolated by using recommended method of the International Humic Substances Society and purified by 0.1M HCl/0.3 M HF solution. Humic acid isolated then were determined ash content, total acidity, carboxilic and phenolic group content and characterized using FTIR spectroscopy.  FTIR analyses of isolated humic acid samples have shown the presence of carboxylic, phenols, alcoholic, amines functional groups, aliphatic hydrocarbon and aromatic ring. The result of ash content determination showed that purification decreased ash content from 5.60% to 1.13%. Total acidity of humic acid was 630 cmol/kg, acidity of –COOH was 226 cmol/kg, and –OH fenolic acidity was 404  cmol/kg.

Abstract

A method of reverse phase-high performance liquid chromatography (RP-HPLC) was evaluated in ascorbic acid determination. The determination was conducted at optimum conditions for RP-HPLC method, including ethanol as mobile phase, flow velocity of 0.8 mL/min, running time of 5 minutes, injection volume of 10 µL, UV detector, wavelength of 245 nm with internal standard of ascorbic acid in metaphosphate-acetic acid. Result of measurement was validated by AOAC Official Method 967.21. It was obtained that RP-HPLC method was high sensitive and precision method due to its limit of detection was 0,5 µg/mL and  RSD  was ≤ 2%. The results of the determination of vitamin C content in fresh ceruring fruit using RP-HPLC method and the titrimetry method namely, 52.9057 ± 0.17 and 54.2066 ± 0.87 mg in 100 g sample, respectively. Based on statistical analysis (t-test), there were no significant differences for the two methods used. The percentage of recovery obtained is excellent in the range of 97.9-104.3%. Therefore, the RP-HPLC method is expected to be an accurate method for routine analysis of vitamin C. Key word: ascorbic acid, reverse phase, HPLC, titrimetric.
