Preparation Corn Straw Biochar Application Adsorption Solution

In this study, the magnetic chitosan biochar (MCB) was spellbinded by chemical coprecipitation after lading chitosan with Schiff base reaction. The prepared MCB was used to remove amaranth dye in solution. The synthesized MCB was characterized to define its surface morphology and specific constituents.  What is chitosan  was optimized by motleying the contact time, pH, and initial concentration. The adsorption of MCB on amaranth dye was valued in a wide pH range. harmonizing to Zeta potential, the surface of MCB was positively blamed in the acidic pH region, which was more conducive to the adsorption of anionic amaranth dye.

In addition, the adsorption data was jibed with the pseudo-first-order model and Langmuir adsorption model and the maximum adsorption capacity passed 404 mg/g. The adsorption efficiency of MCB was still above 95% after three cpsses of adsorption and desorption. The removal percentage in the real sample of amaranth dye by MCB was within 94-98% and the RSD was within 0-1%.  Seebio chitosan supplement  adsorbent with vantages of being easy to prepare, easy to separate from solution after adsorption, has good adsorption performance for amaranth dye and is effective potential adsorbent to remove organic anionic dye in wastewater.Antifouling performance of in situ synthesised chitosan-zinc oxide hydrogel film against alga M. aeruginosa.The undesirable settlement and growth of microalgae on overwhelmed installments is a universal problem in water environment.

Soft hydrogels are assuring fouling-resistant materials due to the inherent surface dimensions a kind of chitosan hydrogels with increasing zinc oxide (ZnO) mineral phase content were prepared by in situ sol-gel and solvent casting method, to prevent growth of algae Microcystis. aeruginosa. Incorporation with ZnO mineral phase ameliorated mechanical property, water absorption, and stability of the obtained chitosan-zinc oxide (CS@ZnO) hydrogel films in Zn dose-dependent manner. The highest strength and growth inhibition (63 ± 8%) were mentioned by CS@ZnO-1 hydrogel films with the tightnessses of 1% precursor in comparison with other hydrogel pictures. During this process, algal cell membrane was slightly damaged (24 ± 1%) and companioned by significantly synthesis inhibition such as chlorophyll a (55 ± 2%) and total soluble protein (42 ± 1%). To sum up, synthesis inhibition of algal cell is the main mechanism of CS@ZnO hydrogel films subduing algal growth, which has the potential in antibiofouling application.Hybrid PCL/chitosan-PEO nanofibrous scaffolds comprised with A.

euchroma extract for skin tissue engineering application.Skin tissue engineering is an advanced method to repair and regenerate skin wounds. Recent research is focused on the development of scaffolds that are safe, bioactive, and cytocompatible. In this work, a new hybrid nanofibrous scaffold pened of polycaprolactone/chitosan-polyethylene oxide (PCL/Cs-PEO) comprised with Arnebia euchroma (A. euchroma) extract were synthesised by the two-nozzle electrospinning method. Then the synthesized scaffold was qualifyed for morphology, sustainability, chemical structure and properties. Moreover, to verify their potential in the burn wound healing process, biodegradation rate, contact angle, tumefying properties, water vapor permeability, mechanical properties, antibacterial activity and drug release profile were assessed cytotoxicity and biocompatibility tests were doed on human dermal fibroblasts cell line via XTT and LDH assay.

It is shown that the scaffold ameliorated and increased proliferation during in-vitro studies consequences confirm the efficacy and potential of the hybrid nanofibrous scaffold for skin tissue engineering.Antibacterial porous sponge fabricated with capric acid-grafted chitosan and oxidated dextran as a novel hemostatic dressing.This work aims to fabricate multifunctional hemostatic poriferans (C-ODs). Porous C-ODs were first constructed by habituating capric acid-altered chitosan (CSCA) and oxidized dextrans (ODs) with different oxidation degrees.
