Waste plastics, such as waste polyethylene terephthalate (PET) beverage bottles and rubber tyres are major municipal solid wastes, which may lead to various environmental problems if they not appropriately recycled. In this study, the feasibility of collectively recycling two types into performance-increasing modifiers for asphalt pavements was analyzed. This study aimed investigate mechanisms PET-derived additives under treatment amines, triethylenetetramine (TETA) ethanolamine (EA),...

Efficient removal of dye pollutants from water is significant importance for environmental protection; thus, the development advanced sorbent materials with high adsorption capacity highly desirable. Herein, we report a large-scale synthesis ceria hollow spheres (CHS) derived sol–gel reaction cerium nitrate on polymeric templates. The obtained CHS have efficient performance to acid black 210 (AB 210), maximum 175.75 mg g–1, which considerably bigger than those previously reported ceria-based...

The adsorption of Cr(VI) on the raw multiwalled carbon nanotubes (MWCNTs) as a function initial concentration, pH, temperature, and MWCNT dosage were studied.The removal from aqueous solution was dominated by redox reaction to Cr(III).The decreased with increasing pH increased rise in temperature dosage.The data MWCNTs could be described well Langmuir isotherm model.The thermodynamic values Gibbs free energy ( G o ), enthalpy H entropy S ) calculated temperature-dependent data, results...

Owing to the toxicity and low biodegradability of aniline in water, its removal usually needs high cost processes such as adsorption advanced oxidation. The degradation characteristics during ozonation were studied. influence operation parameters contact time, initial concentration, ozone dosage, temperature, pH was also investigated. With dosage 22 mg/L, neutral pH, room removed efficiently. After two hours’ ozonation, reached 93.57%, corresponding COD 31.03%, which indicated most...

Various cross‐linked amino starches were used for chromium (VI) adsorption in the environmental protection area. In order to improve adsorption, new starch with porous structure (CPS) was synthesized by reverse emulsion polymerization, using waxy corn after enzyme hydrolysis (ES) as raw material, N,N′‐methylene‐bis‐acrylamide (MBAA) cross‐linking agent, and ceric ammonium nitrate initiator. The effects of volume ratio oil phase/aqueous phase, content emulsifiers, ES, MBAA on swelling,...

The tail wastewater from sewage treatment facilities usually lacks carbon sources, and its subsequent for deep nitrogen removal is difficult in natural conditions. In this study, the constructed wetland (CW) was integrated with microbial fuel cell (MFC) high-density polyethylene (HDPE) fillers as main matrix to improve under inefficient source Compared regular MFC CW systems, MFC-CW attained higher low-carbon influence of influent carbon/nitrogen ratio (C/N) on denitrification...

The acrylic resin leather coating agent modified by nano-SiO 2 is investigated in this article. Nano-SiO prepared the sol–gel reaction from tetraethoxysilane (TEOS) catalyzed with acid and mixed an resin. properties of particles at different aging times are studied. physical–mechanical films sol obtained. Besides, hygiene property finished using measured. Fourier transform infrared spectroscopy (FTIR) transmission electron microscopy (TEM) employed to characterize presence SiO sol. analyzed...

Inorganic hollow spheres have shown their superiority in photocatalytic area due to the large specific surface area, controllable structure and own special optical, electrical, magnetic properties. According classification of inorganic as photocatalysts, recent research progress application status been summarized this paper. At last, future developments field discussed.

A thermally stimulated current (TSC) was used to study the relaxation of polystyrene (PS), ethylene–propylene diene monomer (EPDM), and grafted copolymer EPDM with styrene (EPDM-g-St). The effect measuring conditions on PS is discussed. Some parameters PS, EPDM, EPDM-g-St were calculated in two different ways. In addition, TSC spectra PS/EPDM PS/EPDM-g-St showed that an immiscible system, but there existed a special interaction between plastic phase rubber one blends. compatibility blends...

Although charity has been developed in China for decades, its basic value attributes have not truly stimulated Chinese society. If we look at the development of philanthropy alone, will only fail to touch core problem, but also deviate from it. Based on a brief analysis early history, this paper finds that problem foreshadowed earliest historical development. Through combination qualitative research methods, realizes key improving and even solving problems field public welfare society does...

Abstract High‐performance color‐changing compounds, recognized as prominent smart materials, dynamically alter their color in response to external environmental stimuli. However, existing compounds exhibit limited responsiveness and diversity, presenting challenges the development of textiles responsive multiple This research introduces a novel design for dual‐responsive microcapsules, employing Pickering emulsion template method. The larger compartment encloses photosensitive dyes, whereas...

A novel zwitterionic monomer 3-[(2-acrylamido)dimethylammonio]propanesulfonate (DMADAS) was designed and synthesized in this study. Then it polymerized with acrylamide (AM) by free radical polymerization 0.5 mol/L NaCl solution ammonium persulfate (<TEX>$(NH_4)_2S_2O_8$</TEX>) sodium sulfate (<TEX>$NaHSO_3$</TEX>) as initiator.
