The adsorption of methane on an activated carbon high surface was measured in the range 233−333 K and 0−10 MPa. isotherms showed a considerably different feature than that low carbon. A maximum appeared at relatively temperatures. All experimental were well modeled by Langmuir−Freundlich equation. difference between so-called absolute properly accounted for modeling. An assumption monolayer adsorbate adsorbed included model. layer volume evaluated consistent with pore adsorbent reported CO2...
This paper presents an experimental study on the applicability of microbial induced carbonate precipitation (MICP) to treat municipal solid waste incineration (MSWI) fly ash with high alkalinity and heavy metal toxicity. The experiments were carried out ashes A B produced from processes mechanical grate furnace circulating fluidized bed, respectively. results showed that both types contained CaO content, which could supply sufficient endogenous Ca for MICP treatment. Moreover, S. pasteurii...
Abstract The development of technologies for replacing formaldehyde‐based adhesives and disposing sewage sludge (SS) are two standing issues high interest to the academy industry. This study reports production formaldehyde‐free wood bio‐adhesive using hydrochar from hydrothermal carbonization SS aided by sodium periodate (NaIO4) oxidation. performance bio‐adhesives can meet requirements Chinese National Standard GB/T 9846‐2015 (≥0.7 MPa). aldehyde group forms after NaIO4 treatment hydrochar,...
A microwave-assisted hydrodistillation (MAHD) method was investigated for extraction of essential oils from lavender. The oil extracts at optimized MAHD conditions compared with (HD). Response surface methodology coupled Box-Behnken design applied to optimize the parameters MAHD. were 500 W microwave power, 17 mL/g liquid-to-solid ratio and 40 min time. ANOVA results revealed that time had greatest impact on yield followed by power. Under conditions, 3.19%, approximating predicted (3.20%)....
A rapid and cleanup-free ultrasound-assisted extraction method is proposed for the simultaneous of oxytetracycline, tetracycline, chlortetracycline, doxycycline in manure. The analytes were determined using high-performance liquid chromatography with ultraviolet detector. influence several variables on efficiency procedure was investigated by single-factor experiments. temperature, pH, amount solution selected optimization experiment response surface methodology. calibration curves showed...
The agronomic benefit of biochar has attracted widespread attention to biochar‐based fertilizers. However, the inevitable presence polycyclic aromatic hydrocarbons in is a matter concern because health and ecological risks these compounds. strong adsorption complicates their analysis extraction from In this study, we optimized validated method for determining 16 priority Results showed that accelerated solvent exhibited high efficiency. Based on Box–Behnken design with triplicate central...
The low mechanical strength of a low-calcium fly ash (FA)–red mud (RM) geopolymer severely limits its application. Steel slag (SS) and Ca(OH)2 can provide calcium alkali for the hydration process FA-based geopolymer. In this study, SS was used to replace part RM, introduced. effects on properties FA-RM were investigated. experimental results show that promoted matrix generate more C(N)-A-S-H C-S-H gels optimized pore structure, thereby improving addition 4 wt.% increased products geopolymer,...
The biochar derived from rice hull was evaluated for its abilities to remove hydrogen sulfide (H2S) gas phase. surface area and pH of the were compared. different pyrolysis temperature has great influence on adsorption H2S. At temperature, H2S removal efficiency hull-derived different. capacities 2.09 mg·g–1, 2.65 16.30 20.80 382.70 which their temperatures 100 °C, 200 300 400 °C 500 respectively. Based Yoon-Nelson model, it analyzed mass transfer mechanism by biochar.Implications: paper...
We studied the mechanism by which complete posterior vitreous detachment enzyme-induced vitreolysis alleviates progression of diabetic retinopathy.We enrolled 50 rats and 20 normal control in this study. The right eyes these were treated with a hyaluronidase (5 U) plus plasmin (0.25 intravitreous injection (ET group), while left (DR group) (NC injected balanced saline. Eight months after injection, oxygen concentration was measured, expression levels hypoxia inducible factor-1α (HIF-1α),...
The geosynthetic‐encased vertical column and geosynthetic‐embedded horizontal cushion are recognized as the effective methods to reduce settlement of soft subgrade. This paper investigated behavior a subgrade reinforced by geogrid‐encased stone geocell‐embedded sand using finite element analysis method (Plaxis 2D). simulating was in good agreement with field monitoring data, indicating reasonability designed model adopted parameters. After that, factors, geocell layer cushion, encasement...
The co-pyrolysis of oily sludge and walnut shell is a reliable method for solid waste treatment recycling. In this paper, thermogravimetric analysis was used to study the thermodynamics synergy effect (OS) (WS) at four heating rates (10, 20, 30, 40 °C/min) in temperature range from 50-850 °C. Two model-free methods (FWO KAS) were calculate activation energy. results showed that rate had no significant on pyrolysis process. addition improved process samples. Mixture 1OS3WS effect, while other...
Background: Previous studies have shown the colonoscopy quality affected by endoscopist’s fatigue. This study was aimed to evaluate this potential factor in a colorectal cancer-screening cohort of Chinese patients.Methods: The attendances at department gastroenterology for cancer screening between 2013 and 2015 were retrospectively analyzed. procedure time-of-day hours elapse recorded. primary outcome defined as adenoma detection rate (ADR).Results: A total 1342 colonoscopies performed 19...
