A fluorescence quantitative PCR method for detection of Di-n-butyl phthalate in water sample has been developed. DBP was extract from water samples using liquid-liquid extraction. The binding-DNA which includes specific primers and pUC19 as template were synthesized by conventional PCR. DBP concentration calculates from standard curve between concentrations of DBP and Ct value by SYBR Green. The lowest...
Influence of soil organic matter (SOM) on the adsorption, desorption and transport of polycyclic aromatic hydrocarbons (PAHs) has already been given full investigation in soils. In this paper, High Performance Liquid Chromatography (HPLC) was used to detected and elucidate aqueous leaching of PAHs in different types of soil with soil columns, which enhanced understanding on transport of PAHs appreciably...
A high-performance liquid chromatography with ultraviolet spectrophotometer detection method for the simultaneous determination of oxytetracycline (OTC), tetracycline (TC), chlortetracycline (CTC), and doxycycline (DC) residues in chicken liver was developed and validated. Chicken liver was digested using perchloric acid of 5% mass concentration. The chromatographic separation was performed on an...
This paper is aimed at evaluation about aging properties of cellulose paper used for insulating of oil-filled transformer and analysis on correlation between mechanical characteristic such as tensile strength and chemical characteristics such as CO, CO2 gas and furfural when cellulose paper is aged by thermal. For experiment the accelerated aging cell has been manufactured, it has been aged during...
