Use of amino-modified cotton fibers loaded with copper ions for anionic dye removal under batch and fixed-bed systems: A comparative study

2D Hexagonal Boron Nitride-Coated Cotton Fabric with Self-Extinguishing Property

“…Additionally, the strong binding adhesion between hBN nanosheets and the cotton fabric leads to improved mechanical strength. To confirm this, we performed tensile tests (UTM Instron model 3365), which revealed that the hBN/cotton fabric presented higher strength than pure cotton, as hBN nanosheets restrict interfiber displacements and DETA cross-links the cotton fibers (Figure d) …”

“…To confirm this, we performed tensile tests (UTM Instron model 3365), which revealed that the hBN/cotton fabric presented higher strength than pure cotton, as hBN nanosheets restrict interfiber displacements and DETA cross-links the cotton fibers (Figure 3d). 29 Figure S2a shows, thermogravimetric analysis (Perkin Elmer Pyris Diamond TG-DTA) of cotton showed weight loss of about 5% at a temperature range of 50−80 °C, which is due to the removal of volatile content in the cotton, while there is a sharp decrease in weight from 229 to 375 °C temperature which marks the decomposition of the fibre up to 71% of its weight. In the case of hBN-coated cotton starting with the loss of volatile content (3.5%) at around 50−80 °C, material undergoes the decomposition from 262 to 375 °C by losing about 35% of the total sample weight.…”

Design and application of metal organic frameworks for heavy metals adsorption in water: a review

“…131 Besides, the adsorption equilibrium isotherm is beneficial to provide more information to describe the adsorption mechanism, because it revealed the interaction between the heavy metals adsorbed by MOFs and the quantity of adsorbate that can be tolerated for adsorption on the surface. 132 Hence, numerous isotherm models were used to explain this adsorption mechanism, such as Langmuir, 133,134 Freundlich, 135 Jossens, 136 Hill, 137 etc.…”

Photodegradation of Basic Dyes using Nanocomposite (Silver Zinc Oxide- Copper Oxide) and Kinetic Studies

“…The AZCN (0.05 g for BV16 and 0.1 g for BR18) was added to 800 mL of different dye concentrations (10,20,30 and 40 mg/L).…”

“…The process is begun by ultra violet or visible light irradiation on the semiconductor to excite an electron from the valence band to the conduction band that resulting to formation a high energy electron/hole pair. This pair may directly (or indirectly by generate the radicals) decompose organic compounds (Advanced Oxidation Processes, AOPs) 9, 10 . The advanced oxidation processes (AOPs) is an effective process at the degradation of air, water and wastewater pollutants, especially refractory organic substances 11,5 .…”
