Cation-exchange fast protein liquid chromatography – electrothermal atomic absorption spectrometry (FPLC – ETAAS) was applied for the speciation of trace amounts of aluminium. An aqueous 8 mol dm–3 NH4NO3 linear gradient elution in 10 minutes enabled separation of positively charged monomeric aluminium species in aqueous solution. Separated aluminium species were collected in 0.5 cm3 fractions ...

Fine particulate matter (PM) significantly affects visibility, a sensitive indicator of air pollution. Despite continuous decrease in the PM concentrations South Korea, public generally believes that pollution has worsened over past years. To explain this disparity, we analyzed characteristics recent visibility changes using observations and component data observed Seoul, from 2012 to 2018. A s...

Highlight Research Each species of microalga has a preferable nitrogen source for their optimal growth. The sources in the grown media affected growth rate and biochemical composition Chlorella FNUB01. (NH2)2CO (urea) was found to be best alternative For producing 1 g FNUB01, use urea reduced cost medium by 72.6%. Abstract sp. is potential microalgae produced commercially feed, accelerator, imm...

Abstract. Organic nitrate (RONO2) formation in the atmosphere represents a sink of NOx (NOx = NO + NO2) and termination NOx/HOx (HOx HO2 OH) ozone radical propagation cycles, can act as reservoir transporting reactive nitrogen, contributes to secondary organic aerosol formation. While some fraction RONO2 is thought reside particle phase, particle-phase nitrates (pRONO2) are infrequently measure...

The low seed germination response and seedling growth of crops to salinity is common problem in Pakistan. To overcome this problem,seed priming used as an economic effective approach. Present study was conducted evaluate the effects halopriming ofseeds on germination, yield tomato under saline conditions. seeds variety ‘Raja’ were primed with 0, 50mM 100mM NH4NO3, KNO3, (NH4)2SO4 solutions for ...

Aqueous two-phase systems (ATPSs) are composed of two immiscible aqueous phases that are in equilibrium. As one of the separation methods, aqueous two-phase extraction (ATPE) has advantages of biocompatibility, process integration capability, and large-scale feasibility1. As far as we know, ATPE has been used for the separation of proteins2, enzymes3–4, organic acids5–6, and so on. Based on the...
