Isotherm and Thermodynamic Studies on the Bio Adsorption of Textile Industrial Effluents onto Chitosan Nanoparticle from Macolor Niger (White Snapper)

Abstract

Fish scale wastes are generally discarded in the environment through fish processing industries and local market vendors. It is one of the excellent and efficient renewable bioproducts. Consequently, a number of bioactive compounds have been identified including bioactive peptides, collagen, chitosan, and gelatin which are commercially marketed. The current study involves the extraction and generation of chitosan nanoparticles from fish scales. The synthesized chitosan nanosubstances were categorized by Field Emission Scanning Electron Microscopy (FESEM). The viability of utilizing fish scales as an economical bio-adsorbent for elimination of textile dye was studied on industrial effluent. Fourier transform infrared spectroscopy (FTIR) was used to study the dye adsorption of chitosan nanoparticles before and after the dye treatment. With chitosan nanoparticle treatment of the textile effluents, removal of COD was improved to 80% and the turbidity removal efficiency was improved up to 90%. Thus, the present study provides an excellent bio-adsorbent chitosan nanoparticle generated from fish scales which have potential application as an adsorbent in bioremediation like wastewater treatment.

Molecularly Imprinted Chitosan-Based Thin Films with Selectivity for Nicotine Derivatives for Application as a Bio-Sensor and Filter

“…Despite the promising and evidenced utilization of Chitosan in paper-sizing [ 1 ], the food industry [ 2 ], pharmaceuticals, Veterinary medicine [ 3 , 4 ] medicine [ 5 , 6 ], separation processes [ 7 , 8 , 9 ], and energy systems such as fuel cells [ 10 , 11 ], and at different application sizes such as the Nano and micro scales [ 12 , 13 , 14 ], as well as in the area of molecular imprinting [ 15 , 16 , 17 , 18 ], its extensive use in a diversified industrial economy has been limited due to its hydrophilic nature and narrow application temperature tolerance.…”

Image Analysis to Demonstrate Adsorption and Absorption Processes Through Image Brightness Using Copper(II) Ions and Fish Scales in Teabags: A Colorimetric-Based Analysis

“…Pacific oceans and can reach a maximum length of 75 cm. 31 In the food industry, their hard scales are typically discarded as waste. This waste presents a sustainable opportunity to use the fish scales as biosorbents for managing heavy metal waste in school, university, or industrial chemistry laboratories.…”

“…This waste presents a sustainable opportunity to use the fish scales as biosorbents for managing heavy metal waste in school, university, or industrial chemistry laboratories. 28,31 White snapper was selected for this activity because its relatively larger scales made it easier for students to insert them into the teabags. Students simply dipped the fish scale-filled 240 teabags into the heavy metal solutions.…”

Chitosan: A biopolymer for textile processes and products

“…20 As illustrated on Figure 1, CS could be used in different textile processing steps: fiber spinning, 21 multi-functional fabric finishing, 22 dyeing 23 and textile wastewater treatment. 24 Previous literature works put emphasis only on the use of CS in a specific single textile production step, but our present review reports the application of this biopolymer in many steps of the textile industrial process (fiber formation -fabric treatments -dyeing and printing -textile effluent treatment). In addition, new aspects of CS usage in textile field are presented, such as CS-treated antiviral personal protective equipment (PPE) against SARS-CoV-2, nano-CS, etc.…”
