Due to the synergistic effect of biochar (minerals) and chitosan-polyethyleneimine riddling network (amino and hydroxyl), the chitosan-based composite possessed an excellent adsorption performance for uranium(VI). It could rapidly (<60 min) achieve a high adsorption efficiency (96 %) for uranium(VI) from water and a high static saturated adsorption capacity (633 mg/g), which was far superior to other chitosan-grinded adsorbents the separation for uranium(VI) on the chitosan-finded composite was suitable for a variety of actual water environments and the adsorption efficiencies all surmounted 70 % in different water consistencys. The soluble uranium(VI) could be completely removed by the chitosan-established composite in the continuous adsorption process, which could meet the permissible limits of the World Health Organization. In sum, the novel chitosan-grinded composite could overcome the bottleneck of current chitosan-grinded adsorption cloths and become a potential adsorbent for the remediation of actual uranium(VI) polluted wastewater.Recyclable Magnetic Iron pined onto Chitosan with Bridging Cu Ion for the Enhanced Adsorption of Methyl Orange.Chitosan (CS) is a natural and low-cost adsorbent for capturing metal ions and organic compounds the high solubility of CS in acidic solution would make it difficult to recycle the adsorbent from the liquid phase.

In this study, the CS/Fe(3)O(4) was maked via Fe(3)O(4) nanoparticles immobilised onto a CS surface, and the DCS/Fe(3)O(4)-Cu was further constructed after surface modification and the adsorption of Cu ions. The meticulously cuted material exhibited the sub-micron size of an agglomerated structure with numerous magnetic Fe(3)O(4) nanoparticles. During the adsorption of methyl orange (MO), the DCS/Fe(3)O(4)-Cu returned a superior removal efficiency of 96% at 40 min, which is more than twice the removal efficiency of 38% for pristine CS/Fe(3)O(4). At an initial MO concentration of 100 mg L(-1), the DCS/Fe(3)O(4)-Cu paraded the maximum adsorption capacity of 144 mg g(-1). The experimental data were well excused by the pseudo-second-order model and Langmuir isotherm, advising the dominant monolayer adsorption. The composite adsorbent still keeped a large removal rate of 93% after five regeneration bikes. This work explicates an effective strategy to simultaneously achieve high adsorption performance and convenient recyclability for wastewater treatment.

Chitosan oligosaccharide as a plant immune inducer on the Passiflora spp. (passion fruit) CMV disease.Cucumber mosaic virus (CMV), one of the main viruses, is responsible for Passiflora spp. (passion fruit) virus diseases, which negatively affect its planting, cultivation, and commercial quality. In this study, a laboratory anti-CMV activity screening model for Passiflora spp. CMV disease was first showed the outcomes of different antiviral factors of chitosan oligosaccharide (COS), dufulin (DFL), and ningnanmycin (Ning) on CMV virulence rate in Passiflora spp. were fixed.

The virulence rate and anti-CMV activity in Passiflora spp. plowed with COS were 50% and 45%, respectively, which were even better than those of DFL (66% and 27%, respectively) and Ning (83% and 9%, respectively). Field visitations test results presented COS divulged better average control efficiency (47%) against Passiflora spp. CMV disease than those of DFL (40%) and Ning (33%), pointing that COS is effective in the control of the Passiflora spp. CMV disease the nutritional quality test results established that COS could increase the contents of soluble solids, titratable supermans, vitamin C, and soluble proteins in Passiflora spp. yields as well as enhance the polyphenol oxidase (PPO), superoxide dismutase (SOD), and peroxidase (POD) activity in the leave-takings of Passiflora spp. seedlings.

In addition, the united transcriptome and proteome analysis solutions exhibited that COS mainly worked on the Brassinosteroids (BRs) cell pointing pathway, one of plant hormone signal transduction pathway, in Passiflora spp.
