“…Carboxymethyl chitosan dialdehyde starch Schiff alkali metal complex was prepared by reaction of carboxymethyl chitosan dialdehyde starch with 0.05 mol L −1 metal salt solution (copper sulfate, silver nitrate, nickel nitrate, and zinc nitrate) in a beaker at 25 °C for 6 h, [ 44 ] and then filtered and dried at 50 °C for 2 h in a vacuum drying oven. The adsorption capacity of copper, [ 34 ] nickel, [ 34 ] and zinc [ 34 ] was determined by EDTA titration, and silver[I] was titrated by potentiometric titration with potassium bromide.…”

Carboxymethyl chitosan dialdehyde starch Schiff base (CMCDAS) and its metal complexes were synthesized by corn starch (St), sodium periodate, carboxymethyl chitosan and metal ions (copper, zinc, nickel, silver), and were characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), thermogravimetric analyzer (TGA), energy dispersive spectroscopy (EDS) and X-ray powder diffraction (XRD). The antibacterial activities of CMCDAS against E. coli and S. aureus increased according with its increasing nitrogen content, and the best minimum inhibitory concentrations (MIC) to E. coli and S. aureus were 30 mg/mL, respectively. Furthermore, the minimum inhibitory concentrations (MIC) of the metal Complexes (copper, nickel, silver, and zinc) against S. aureus were 7.50 mg/mL, 30 mg/mL, 30 mg/mL, and 1.88 mg/mL, respectively; and against E. coli were 7.50 mg/mL, 15 mg/mL, 15 mg/mL, and 0.94 mg/mL, respectively.

“…An STD Q600 thermogravimeter (TA Instruments, Co., Ltd., Newcastle, DE, USA) was used to determine the pyrolysis characteristics and thermal stability in the Ganoderma carbon samples [25]. A 10-mg carbon sample in an alumina crucible was weighed and heated from 30 °C to 800 °C at a heating rate of 10 °C/min under a nitrogen atmosphere.…”

This study aimed to prepare Ganoderma-based activated carbons for chemical adsorption and catalyzing N-(phosphonomethyl)iminodiacetic acid to glyphosate. The activated carbons were prepared by applying different activation conditions. These carbon samples were applied to catalyze N-(phosphonomethyl)iminodiacetic acid to glyphosate. The results showed that the black Ganoderma char activated at 800 °C for 90 min using 40% phosphoric acid had the highest methylene blue adsorption capacity and DPPH scavenging activities, but the methylene blue adsorption capacity of the black Ganoderma sample activated at 800 °C for 90 min using 40% acid-base solution was lower than the red AC sample. These carbon samples had high thermal stability. Chemical modifications of these chars with the carbon modifiers at an optimized activation condition increased the Langmuir-specific surface areas of these carbon samples up to 2055.09 m 2 /g. The carbon sample of black Ganoderma activated using the 40% acid-base solution at 800 °C for 90 min and coupled with the addition of hydrogen peroxide during ultrasonication and microwave-assisted reactions had the highest glyphosate catalyzing rate. The glyphosate yield obtained from the catalyzing at atmospheric pressure was 58.78 ± 0.28%. These Ganoderma-based activated carbons can replace other carbon materials for catalysis applications and as adsorbents in food and pharmaceutical industries.
