Abstract:
Abstract Phenolic compounds are produced in thermal cracking processes, drugs and herbicides synthesis and other industrial processes. Such compounds exhibit high toxicity for aquatic environment and for aquatic life. So, due to their high toxicity is important to treat waters with phenols content. For the treatment of waste waters containing phenols or phenolic compounds several unconventional methods are applied, such as: inverse osmosis, coagulation, solvent extraction, flotation–coagulation combined processes, adsorption, and anaerobic processes. From all used remediation processes adsorpt

Abstract:
Although hindered phenol/polymer-based hybrid damping materials, with excellent damping performance, attract more and more attention, the poor stability of hindered phenol limits the application of such promising materials. To solve this problem, a linear hindered phenol with amorphous state and low polarity was synthesized and related polyurethane-based hybrid materials were prepared in this study. The structure and state of the hindered phenol were confirmed by nuclear magnetic resonance spectrum, Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD). The existence of i

Novel polymeric photosensitizers for singlet oxygen production in water are described. The polymers contain rose bengal (4,5,6,7-tetrachloro-2',4',5',7'­tetraiodo-fluorescein) chromophores covalently attached to the polymer chain. The quantum yields of singlet oxygen formation and photooxidation of phenol in water have been determined. The methods of separation of photosensitizer from the reactants after completion of reaction have been established.

Abstract:
The ubiquitous presence of phenolic compounds in effluents poses a risk to aquatic organisms and human health. This study investigates the responses of the emerging algal-bacterial granular sludge process in treating phenolic wastewater. The results showed that phenol at 1, 10, and 100 mg/L had little effect on ammonia-N, chemical oxygen demand (COD), and phosphate-P removal. At the highest phenol concentration of 100 mg/L, the average removal rates of ammonia-N, COD, and phosphate-P were 94.8%, 72.9%, and 83.7%, respectively. The presence of phenol led to a decline in chlorophyll content of t

The breakthrough capacity of GQ-1 was 2.53 times that of XAD-4 when the effluent concentration reached 5mg/L.

Enzymatic phenol removal from wastewater is an important treatment approach to promote environmental sustainability. Whilst free peroxidases demonstrate efficient phenol degradation capabilities, they are disadvantaged by long-term stability and reusability. This research develops a novel system of plant-based peroxidase encapsulated in polymeric capsules for continuous phenol removal in a fluidized bed column. The process demonstrated scalability and commercial viability with 95% phenol removal efficiency.

Abstract:
The flocculation of three colloidal dispersions (precipitated calcium carbonate (PCC), T’02 and a calcined clay) using a combination of polymeric flocculants and cofactors was investigated. The flocculants used were PEO (MW = 9×10′), CPAM (a cationic copolymer of acrylamide) and POLYPAM-CO-PEG (a non-ionic comb copolymer (MW = 5×100 consisting of a polyacrylamide backbone with – I mole % pendent PEG chains). The cofactors were based on polyvinyl phenol-co-sodium acrylate) and polyvinyl phenol-co-sodium styrene sulfonic acid). The amount of flocculation induced was dependent on the components p

Abstract:
Our previous work indicated that suspension-cultured plant cells show remarkable flexibility in altering cell wall structure in response either to growth on saline medium or in the presence of the cellulose synthesis inhibitor 2,-6-dichlorobenzonitrile (DCB). We have continued to analyze the structure of these modified cell walls to understand how the changes modify wall strength, porosity, and ability to expand. The major load-bearing network in the walls of DCB-adapted dicot cells that lack a substantial cellulose-xyloglucan network is comprised of Ca2+-bridged pectates; these cells also hav

Abstract:
Our study was designed to elucidate the chemical determinants of pectin cross-linking in developing fruits of apple and peach and to evaluate the role of breakage cross-linkages in swelling, softening, and cell separation during the ripening. Peaches cell walls soften and swell considerably during the ripening, whereas apples fruit cells maintain wall firmness but cells separate during late stages of ripening. We used a "double-reduction" technique to show that levels of non-methyl esters of polyuronic acid molecules were constant during the development and ripening and decreased only in overr
