Abstract:
Adsorption is a process of absorption of adsorbate or substances absorbed by the surface of the adsorbent or absorbent substance which aims to reduce the Fe3+ cation in a solution. Research has been carried out on the adsorption of Fe3+ cations using silica sulfonate adsorbents by varying the pH and contact time to obtain optimum conditions during adsorptions. The adsorption process of Fe3+ cations used a sulfonate modified silica gel adsorbent has been carried out by varying the pH, namely 2; 3; 4; 5; 6; 7 and the maximum pH has been fixed at pH 6 with an abdorption capacity of 2,32732 mg/g w

Abstract The trigeneration systems for production of cold use sorption refrigeration machines: absorption and adsorption types. Absorption systems are characterized namely by better cooling coefficient of performance, while the adsorptive systems are characterized by the ability to operate at lower temperatures. The driving heat source temperature can be as low as 60-70 °C. Such temperature of the driving heat source allows to use them in district heating systems. The article focuses on the presentation of the research results on the adsorption devices designed to work in trigeneration systems

In our work, the transition-metal-oxide precursor (TMO@BC, M = Fe, Co, Ni) has been loaded on the pollen carbon by the hydrothermal method and annealed at different temperatures to generate a composite material of metal oxide and pollen carbon in this study, which can effectively prevent agglomeration caused by a small size and magnetism. The XRD patterns of the samples showed that the as-synthesized metal oxides were γ-Fe2O3, CoO, and NiO. In the 20 mg/L methyl orange adsorption experiment, the adsorption amount of CoO@C at 500 ℃ reached 19.32 mg/g and the removal rate was 96.61%. Therefore,

The adsorption performance of Cr (VI) on activated sludge and the effect of adsorption time, pH, temperature on the adsorption and desorption were studied. The initial pH is important for biosorption, and the optimum effect on Cr (VI) biosorption is acquired within initial pH of 0.5-1.0. Activated sludge has high efficiency of treating low concentration Cr (VI) wastewater. The removal rate of Cr (VI) could reach 99% when the total concentrations of Cr (VI) were 10 mg/L. The results of static test showed that the adsorption equilibrium was reached within 60 min. The biosorption process was fitt

Abstract:
AbstractCesium in soil exists in two forms. The soil in Fukushima Prefecture contaminated with radioactive cesium was classified into two fractions: the fraction of cesium with weak adsorption to soil (F1), and the fraction of cesium with strong adsorption to soil (F2). We evaluated the absorption of Cs by different crops (rice, soybean, and buckwheat) in different soil fractions by measuring the 133Cs and 137Cs concentrations in the soil and crops. We also evaluated the effect of potassium fertilization on cesium suppression in different soil fractions.Without K fertilization, 137Cs was absorbed mostly from the F1 fraction by all three crops; 133Cs was absorbed mostly from the F2 and F1 fractions by soybean and buckwheat, respectively, and from both F1 and F2 fractions by rice. Potassium fertilization decreased the percentages of both 137Cs and 133Cs absorbed from the F2 fraction by soybean. In contrast, buckwheat presented reduced absorption from the F1 fraction. In rice, the uptake of cesium by fraction did not change with or without potassium fertilization, indicating that different crops absorb cesium from different soil fractions.

In both cases, the principal idea was to design and operate a dedicated air collection system that would be used for the treatment of the gases, and that would work independently from the general ventilation system.
