Chitosan, dissolved in acetic acid, was used for the coagulation鈥揻locculation of an anionic dye (Reactive Black 5). In acidic solutions protonated amine groups of chitosan attract dye sulfonic groups. Increasing chitosan dosage increases dye removal up to a concentration resulting in complete ...
Chitosan was applied directly to the leaves of sorghum plants on day zero of water deficit, using a chitosan solution prepared in accordance with the methodology described by Korsangruang et al. (2010), with some modifications. The solid chitosan was dissolved in acetic acid (0.25% v/v) with...
Preparation of chitosan/PEI-grafted magnetic gelatin is shown in Fig. 1. Chitosan was firstly oxidized by potassium periodate to obtain the dialdehyde chitosan, which was prepared based on the literature with a slight modification28. Briefly, chitosan was dissolved in acetic acid (0.2 mol ...
Composite biosorbents were formulated by mixing chitosan powder (5 g) with activated sugar bagasse ash (1 g) dissolved into acetic acid (7%) (240 mL) and left for 16 h. The slurry was poured into an alkali coagulating solution (H2O: methanol: NaOH = 4:5:1, w/w/w) (200 mL),...
Firstly, chitosan (CS) was dissolved in acetic acid solution (1%, v/v) and continuously stirred to obtain a transparent chitosan solution (2 wt%). Then, 1 wt% NFC suspension was Preparation and characterization of the CS/NFC aerogel In order to produce the aerogel with highly oriented...
CSNPs were prepared via the ionotropic gelation method as described [52,53,54]. Briefly, 1.7mM (CS; Mw ~ 190–370 kDa, deacetylation ≥ 70%) was dissolved in 1% acetic acid. Then, 1.3mmol/L GSH solution was added to the suspension and allowed and mixed on a magnetic stirrer...
BCH (bulk chitosan, 0.01%) dissolved in 0.1% acetic acid. CuSO4 (0.01%) and fungicide (0.01% of Bavistin). Full size image Effect of Cu-chitosan NPs on CLS disease in pot experiment In pot experiment, symptoms of CLS disease initiated after 3–4 days of fungal inoculation in control ...
Two different deacetylated chitosans were dissolved in formic, acetic, lactic, or propionic acid to prepare chitosan films. The pH values of the film-formi... KM Kim,JH Son,Sung㎏oo Kim,... - 《Journal of Food Science》 被引量: 107发表: 2010年 Chitosan nanoconstructs for improved oral ...
Chitosan was dissolved in degassed distilled water containing 1% of acetic acid. 0.50 g of chitosan was dissolved in 30.0 ml of distilled 1% acetic acid solution. The reactor was placed in a water bath preset at 60 °C, then 0.10 g of potassium per sulphate (KPS) as an initiator was add...
The emulsion so formed was mixed with equal volume of 0.1 % chitosan dissolved in 0.1 % acetic acid. The mixture of SLNs with chitosan was stirred for 2 h. The resulting chitosan-SLNs were centrifuged and pellet was collected. The c-SLNs were lyophilized in a freeze dryer (Labconco, ...
