In this study, chitosan-modified bentonite was synthesized using the coprecipitation method. When Na2CO3 content 4% (weight of soil) and mass ratio chitosan to 1:5, adsorption performance chitosan/bentonite composite best. The adsorbent characterized by scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, Brunauer-Emmett-Teller measurement. Various characterization results demonstrate that successfully entered interlayer increased layer spacing but did...
The application of the bacterial dissimilatory nitrate reduction to ammonium (DNRA) process for treating nitrate-rich wastewater offers an environmentally friendly and resource-efficient strategy with significant potential nitrogen recovery. This study investigates impact carbon sources, C/N ratios, pH, temperature on DNRA efficiency Pseudomonas sp. strain LZ-1 (strain LZ-1). results revealed that sodium citrate is most favorable source among formate, acetate, propionate, enhancing in LZ-1....
Industrial wastewater contains complex pollutants, including toxic dyes, necessitating effective and sustainable remediation strategies. Conventional treatment methods often struggle to remove multiple dyes simultaneously, underscoring the need for innovative adsorbents. This study investigated a clay/carbon composite (SBE/C (500 °C)) derived from spent bleaching earth (SBE) via pyrolysis simultaneous removal of methylene blue (MB) malachite green (MG) dyes. The process significantly...
A composite packing material (CM-5) was prepared in this study, mainly consisting of compost with functional microorganisms, calcium carbonate (CaCO3), perlite, cement and plant fiber. To get stronger compressive strength, mass ratios these components were optimized based on single factor experiments, finally adding amounts cement, fiber, CaCO3, binder at 18%, 7%, 13%, 17% 27%, respectively. According to the optimum proportion, CM-5 extruded cylindrical shape (12 mm diameter 20 length) a...
For preoperative analgesia during a variety of operations, the erector spinae plane block (ESPB) has grown in popularity. However, its effectiveness lumbar surgery is still unknown. The purpose this study was to investigate potential benefits ESPB enhancing analgesic efficacy elderly individuals following posterior spine surgery. Patients aged 65 years or older who underwent elective instrumented fusion (with without decompression) at our institution between January 2019 and June 2022 were...
The “sol–gel method” was used to prepare spherical chitosan-modified bentonite (SCB) hydrogels in this study. SCB were characterized and as sorbents remove tetracycline (TC) from aqueous solutions. adsorbents by SEM, XRD, FTIR, TG, BET techniques. Various characterization results showed that the adsorbent had fewer surface pores a specific area 96.6% lower than powder, but layered mesoporous structure of remained unchanged. adsorption process fit both Freundlich model pseudo-second-order...
In this study, nitritation–denitrification SBR was successfully begun within 5 days by maintaining a proper condition (pH > 8, DO 0.1–0.5 mg/L and 29.5 ± 0.5°C) transient excessive aeration would not cause N-NO3- accumulation. the start-up stage, FA had an upward trend reached to 10.98 mg NH3/L, which could entirely inhibit NOB. On basis of experimental evidence, ORP showed regular trends variation first derivatives as process control parameters in proposed. During real-time period, N-NH4+...
The black-odor water body restoration is an unfinished business in protecting and maintaining the ecological functions of natural systems China. Magnetic coagulation (MC) had found a vast application prospect for its high-efficient separation. In this work, performance MC was analyzed to explore role protection, with focus on identification removal mechanisms dissolved organic matters (DOM) by absorption fluorescence spectroscopy terms spectroscopic indices, two-dimensional correlation...
ABSTRACT Waste treatment for pollution control is a hot topic being studied and has received growing attention. In this study, spent bleaching earth (SBE), waste material from the oil refineries, was pyrolyzed in N2 atmosphere to produce an environmentally sustainable clay/carbon composite (SBE@C (500 °C)). SBE@C °C) tested its ability remove methylene blue (MB) water. The Langmuir model best explained adsorption isotherms, with maximum capacity of 29.54 mg/g (MB solution (10–60 mg/L))....
A new type insulation resistance on-line monitor has been designed for Hybrid Electric Vehicle (HEV). It is mainly composed of a proportional circuit and data sampling, processing module.

These are isolated opto-coupler Isolation amplifier transmitted to ECU. value calculated in hardware circuit, software realization calculation formula have given....
Sulfur-based materials are widely used as electron donors for denitrification to enhance nitrogen removal from water. This leads an increased sulfate concentration in the effluent or accumulation recirculating aquaculture systems. study explored acute and chronic toxicity of juvenile zebrafish (
In this study, the interactions between daidzein and methanol were studied to investigate isoflavone extraction. The complexes of MeOH–daidzein = 1:1, 2:1, 4:1, 7:1 using DFT/B3LYP-D3. According findings can act as a hydrogen bond donor well an acceptor. Binding energies demonstrate that more MeOH molecules interacting with could give stability system. strengths bonds reveal prefers than atoms in (AIM) topological analysis was performed analyze nature bonds. Moreover, daidzein, genistein,...
An improved drop-sphere-forming (IDSF) method was applied to synthesise chitosan resin. Chitosan resin synthesised by the self-made device and cross-linked with epichlorohydrin.
