The removing of the acetyl group makes chitosan is soluble in most diluted acid solution such as acetic acid, formic acid and lactic acid [5], [6]. Thus, in this study, a facile process was proposed to extract chitin and chitosan from shrimp shell for synthesizing chitosan film with excellent and robust properties.

An innovative system for extracting cellulose nanocrystals (CNCs) was proposed that uses a two-step process that combines short-time pretreatment by electron-beam irradiation (EBI) in the solid state and disintegration using high pressure homogenization (HPH) and was compared with the classic production by t

Herein, a new kind of magnetic covalent organic frameworks (MCOFs), named MCOF-DhaTab, using 1,3,5-tris (4-aminophenyl) benzene and 2,5-dihydroxy-1,4-phenylenedialdehyde as functional monomers of COFs and Fe 3 O 4-NH 2 nanoparticles as magnetic carrier was synthesized at room temperature through Schiff base reaction. …

Novel porous covalent organic frameworks (COFs) were synthesized via a facile approach at room temperature by using 1,3,5-tris(4-aminophenyl)benzene and 2,3,5,6-tetrafluoroterephthalaldehyde as two building blocks for the first time. And the COFs were applied as dispersive solid phase extraction (dS …

Natural melanin biopolymers have multifarious activities, but their commercial exploitation is obstructed due to their high price, unsustainable source, use of harmful solvents, and low extraction yield. Conventional techniques for the extraction of the melanin biopolymer encounter several disadvantages such as poor extraction efficiency, excessive use of …

A facile and efficient approach to prepare carboxylated cellulose nanocrystals (CCNCs) is presented through a novel one-step hydrothermal procedure by using a mixed acid system of hydrochloric acid and nitric acid (HCl/HNO3). The as-prepared cellulose nanoparticles were characterized by scanning electron microscopy, wide angle X-ray diffraction, …

Traditionally, vanadium extraction from slag has relied on the sodium roasting-water leaching process. This involves blending the vanadium slag with sodium salts and heating to high temperatures (750–850 °C) to form sodium vanadate [6], [7]. ... A facile new process for the efficient conversion of spent LiFePO 4 batteries via (NH 4) 2 S 2 O ...

Facile enrichment and determination of trace organophosphorus pesticides (OPPs) in foods has been a constantly pursuing goal in food safety field. ... After filtration, the filtrate was collected. The extraction procedure was repeated three times. Then the combined filtrates were evaporated to dryness at 50 °C with nitrogen stream. The dried ...

Chitin could be extracted from crab shells using a combination of chemical and biological methods, and the purity of the extracted chitin reached 89.79%; cultivation of Bacillus velezensis using extraction waste liquid can induce the synthesis of stable BV; the maximum drug loading of BV towards DOX was 447.58 mg/g and its adsorption …

A detailed investigation of choline chloride-lactic acid (ChCl-LA)-based deep eutectic solvent (DES) extraction of lignin nanoparticles from herbaceous biomass (wheat straw) was conducted. It was found that DES can extract high purity lignin (up to 94.8%) with a high yield (up to 81.5% from air-dried samples and 85.9% from oven-dried samples) …

To obtain CNCs from purified cellulose, various extraction processes have been studied to break down structure of fibers by acid hydrolysis, enzyme hydrolysis, or TEMPO oxidation. 21 In terms of sulfuric acid hydrolysis, both the concentration of the sulfuric acid and the hydrolysis time affect the morphology, structure, and crystallinity of ...

On peut différencier 3 grandes techniques. La cyanuration est une méthode basée sur la solubilité de l'Or. Après le concassage de minérais, on l'immerge dans une solution de …

L'extraction d'or est un processus en plusieurs étapes utilisant différentes techniques selon le type de gisement, l'exploitation et l'approvisionnement en or. Il existe généralement deux types de minerais d'or. L'or primaire est dans de la roche ou dans un filon d'or, …
