Abstract Mercury (Hg) contamination has become a serious threat to ecosystems. Amelioration technology for soil is expected control the specific interactions between N in ex-gold mining contaminated with Hg. This research aimed analyze interaction of Hg-N on ameliorated sub-bituminous coal and activation 10% NaOH. The experimental design used this study was Completely Randomized Design three re...

Emulsion of waxy crude oil is one of the common states in the subsea pipeline. At low temperatures in offshore environment, waxy crude oils with water could form the crude oil emulsion gel of oil-in-water emulsion. Thus, the waxy crude oil emulsion viscoelastic behavior for deep sea transportation and restarting pipeline safety is particularly important. By means of MASIII HAAKE rheometer which...

Extraction of nickel and its co-extraction with copper from ammoniacal media into emulsion liquid membrane systems (ELMs) was investigated using LIX 84I as the carrier. Measurement of the solute stripped in the internal phase of emulsion opened a new dimension in the study of the ELM extraction processes. The effect of operating parameters such as feed pH, initial feed concentration, and treat ...

The purpose is to prepare 2% w/v emulsions of dodecafluoropentane, perfluorodecalin, and perfluoroctylbromide and compare them for their ability to absorb oxygen. The oxygen uptake capability and volume expansion of each emulsion and the blank vehicle were evaluated in water at 21 degrees C and 37 degrees C. The average particle size of the dodecafluoropentane emulsion is < 400 nm stored at roo...

Aim of the present study was to characterize the process of atomization and drying of layer-by-layer emulsions containing lecithin (single layer emulsion) and lecithin/chitosan (multilayer emulsion) and the oxidative stability of the spray-dried emulsions during storage. For this purpose, the analysis of the emulsion spray droplet size during atomization by two different atomization devices, i....

Phenol emulsion reassociation technique (PERT) greatly enhances the rate of DNA hybridization in solution over typical hybridization conditions (1) and has successfully been used to accelerate competitive DNA reassociation for performing subtraction based genomic cloning (2-5). PERT is accomplished through the establishment and maintenance of a phenol emulsion, typically by mechanical vortexing...
