an innovative method based on the membrane bioreactor (mbr) technology was developed as a potential remedy for the water shortage. mbrs attracted much attention in the field of wastewater treatment and reuse. it is reported from many researchers that membrane bioreactor technology is feasible and an efficient method for the treatment of wastewater. however, mbrs are faced to membrane fouling whic...

The development of compounds with a better antibacterial activity is highly needed. One way to achieve this by modifying the structure compound using chitosan as starting material, because its abundant natural source in Indonesia, biodegradable properties, and where free amines are present. This study aims obtain Mn(II) -Carboxymethyl Chitosan Schiff Base-Salicylaldehyde complex increase agains...

We present here the synthesis of a highly O-carboxymethylated chitosan derivative. First, an improvedprotocol for the two-step synthesis of N-trimethyl chitosan (TMC) from chitosan was developed, yield-ing a maximum degree of quaternization (DQ) of up to 46.6%. Successively, the chitosan derivativeO-carboxymethyl-N-trimethyl chitosan (CMTMC) was synthesized from the TMC obtained by applyingan o...

The aim of this study was to develop and characterize an intranasal delivery system for amantadine hydrochloride (AMT). Optimal formulations consisted of a thermosensitive polymer Pluronic® 127 and either carboxymethyl cellulose or chitosan which demonstrated gel transition at nasal cavity temperatures (34 ± 1°C). Rheologically, the loss tangent (Tan δ) confirmed a 3-stage gelation phenomena at...

n-sodium acrylate-o-carboxymethyl chitosan [cmch-g-paa(na)] bound fe3o4 nanoparticles were developed as a novel magnetic nanoparticles with an ionic structure that can be potentially used in many fields. cmch-g-paa (na) was obtained by grafting of sodium polyacrylate on o-carboxymethyl chitosan, which is an amphiphilic polyelectrolyte with the biocompatibility and biodegradability properties. a...

We examined the effects of four kinds of chitosan derivatives on initial adherence of oral bacteria onto human anterior teeth surfaces. The buccal surfaces of anterior teeth were used as the experimental surfaces. They were divided into five rectangle areas with outer dimensions of about 2 mm x 4 mm. After applying two ml of a sample solution onto the tooth surfaces, an examiner wiped each rect...

A novel chitosan-based biopolymer dye possessing antibacterial properties was synthesized by reaction of O-carboxymethyl chitosan and Acid Red GR. The synthesized materials were characterized by Fourier transform infrared spectroscopy (FTIR), degree of substitution (DS), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TG), X-ray diffraction (XRD), water solubility test, anti...

The Carboxymethyl chitosan Schiff base (CSB) derivative and its cobalt and nickel complexes (CSB-Co & CSB-Ni) have synthesized. The FTIR results showed the interaction with the amine of Carboxymethyl chitosan and aldehyde confirming the Schiff base formation. The XRD results, in comparison to CMC, displayed weaker peaks, which shows a decrease in crystalline properties and also exhibits the amo...

The presented studies are focused on the dependence of paper sheet strength properties on the composition of additives, chitosan, cyanoethyl and carboxymethyl chitosan. Chitosan and its derivatives achieve an improvement in the strength properties of unagged and agged paper sheets. Also, cyanoethyl chitosan improves the dielectric properties of the treated paper sheets. The dielectric study was...

The data presented in this article is related to the research article entitled "Paclitaxel loaded magnetic nanocomposites with folate modified chitosan/carboxymethyl surface; a vehicle for imaging and targeted drug delivery" (S. Bano, M. Afzal, M.M. Waraich, K. Alamgir, S. Nazir, 2016) [1]. It contains the absorbance spectra, band gap energies of pure nickel-ferrite nano cores (NFs), and calibr...
