Abstract Studies indicated that duckweed absorbed mercury in water (e.g. lakes) strongly and after three days it contained up to 2000 ppm of by weight duckweed. The uptake was little affected acidity at pH 4.0 5.0. presence copper ion suppressed the significantly. 1.0 mM EDTA solution also Further 10 mg humic acid 400 mL some degree, probably complexing mercury.
Abstract The uptake of Al3+, Cu2+ and Pb2+ from aqueous solution by duckweed has been observed at pH 4.0, 4.5, 5.0. results showed that the was much faster than Al3+ Cu2+. suppressed presence Al3+. proportion metal (PMUT) dependent on concentration in when only one kind ion present. It decreased increasing concentrations other metals mixtures solutions. always less loss content 1n relevant solution. This fact implied process ions may involve two stages. In first, is absorbed but then later...
Objectives:This study evaluated the potential of recycled activated carbon from household water purifiers as an adsorbent for removing methylene blue. It aimed to achieve resource recycling and dyeing wastewater treatment through sonication modification carbon.Methods:After sieving a particle size 75-150μm, material, in this paper referred PCB-S, was processed using enhance its adsorption capacity. The characteristics PCB-S were analyzed SEM, XRD BET analysis. To evaluate efficacy,...
Abstract Studies on duckweed extract indicated that at least some of the magnesium in chlorophyll was replaced by copper. The copper combined not only with chlorophyll, but also other plant pigments duckweed. study demonstrated HPLC‐AA can be used to speciation and duckweed, revealing total number such compounds present associated organic compounds. has potential extensive application many fields science. To obtain information needed electronic spectra chromatograms three samples treated...
Objectives : To recycle the wasted activated carbon from water purifiers and reuse stormwater runoff, this study evaluated quality of runoff with regeneration using granular containing commercial for treatment household purifiers.Methods The removal total coliforms, chloride, BOD, T-N, T-P, turbidity, pH in were analyzed by down-flow column test varied mixing ratios. In addition, chemical modification ferrous sulfate ultrasonic conducted to improve efficiency turbidity.Results Discussion...
