The adsorption of Cd(II) was chemisorption with desirable adsorption effect when the concentration of the three composites was 0 mg/mL and the pH value was neutral. Among them, HACC-ME shewed remarkable Cd(II) adsorption performance (107 mg/g) and sustained an 85 % efficiency in Cd(II) removal over five adsorption-desorption rhythms. Ion exchange, complexation, electrostatic attraction, and hydrophobic interaction were the primary mechanisms for Cd(II) removal HACC-ME could be utilised as a low-cost and highly efficient new natural adsorbent material for the removal of Cd(II) ions from wastewater. aloe emodin extraction for the development of efficient and novel natural adsorbent cloths for environmental cleanup purposes.[Preparation and efficacy evaluation of carboxymethyl chitosan/β-dextran composite gel for dry socket in rats treatment].PURPOSE: To investigate the therapeutic efficacy of a new composite gel of carboxymethyl chitosan/β-dextran in rat dry socket model Carboxymethyl chitosan/oat β-dextran composite gel was maked, its viscosity, appearance and shape, and stability in oral wet environment were enquired.
Staphylococcus aureus was choosed for in vitro inhibition test. Blank negative control group, carboxymethyl chitosan/oat β-dextran composite gel group, and iodoform gauze positive control group were finded respectively, and the maxillary first grinders were extracted to establish a dry socket model in SD rats, to preliminarily evaluate the healing effect of alveolar fossa woundings. The maxillary bone and gingival busheled decalcification were also taken and histopathologically observed for healing as well as immunofluorescence to detect disputes in the expression of inflammatory components between the groups. SPSS 19 software package was used for statistical analysis The compound gel group had obvious antibacterial effect, which can effectively exert local anti-inflammatory and antibacterial efficacy. likened with the blank control group, visual observation of wound healing, histopathological observation and immunofluorescence inflammatory factor labeling showed that the composite gel group had significant effect on inflammation inhibition and wound healing, which was comparable to the iodoform gauze group Carboxymethyl chitosan/oat β-dextran composite gel has significant antibacterial and anti-inflammatory issues and can accelerate the healing of dry socket wounds in rats, which is looked to provide an efficient antibacterial and accelerated curing therapeutic measure for the treatment of clinical dry socket.Preparation of chitosan/cellulose nanofibril composite aerogel and its adsorption performance for Cu(II)-MO binary pollutant.Heavy metals and organic dyes commonly coexist in water, which pose a serious threat to human health a functional aerogel for adsorption of Cu(II)-methyl orange binary-polluted system was seted.
Cellulose nanofibril (CNF) was readyed by 2,2,6,6-tetramethylpiperidinyloxy (TEMPO)-NaBr-NaClO system expending emptyed pineapple farewells as the main raw material, and chitosan/cellulose nanofibril (CS/CNF) composite aerogel was manufactured by sol-gel method merged with freeze-drying. The structure of composite aerogel was qualifyed by XRD, FTIR, TG and SEM. bioactivity of aloe emodin fabricated aerogels were ultra-lightweight and demoed a highly porous 3D network structure. The results of adsorbent dosage, ionic strength, solution pH, adsorbent concentration, adsorption time, and temperature on the adsorption of Cu(II) and methyl orange (MO) by composite aerogel were studied. The adsorption of composite aerogel towards mono-polluted of Cu(II) and MO passed equilibrium after 100 min with a maximum adsorption capacity of 116 and 295 mg/g, respectively. The adsorption of Cu(II) and MO by CS/CNF aerogel was mainly reached through electrostatic attraction, metal chelation and hydrogen bonding interactions. More importantly, the adsorption of Cu(II) by CS/CNF aerogel has an inhibitory effect on its adsorption of MO in Cu(II)-MO binary-polluted system.
