Lotus leaf powder (LLP) was chemically modified with dimethylamine (DMA) to achieve a tertiary amine type powder, named DMA-LLP, and used as an adsorbent for the removal of Reactive Red 195 (RR 195...

Aminated avocado seed powder (AASP)—an eco-friendly novel adsorbent has been used for the removal of Acid Yellow 17 (AY 17) and Amaranth (AMR) from an aqueous phase. The AASP (before and after adso...

In this study, we used a simple and low-toxicity chemical treatment to make a carboxylate-functionalized dragon fruit peel powder (CF-DFPP) from dragon fruit peel to improve its capacity for adsorbing Rhodamine B (RhB) from an aqueous medium. Field Emission-Scanning Electron Microscopy/Energy-Dispersive X-ray (FE-SEM/EDX), point of zero charges (pH

Turkey tail (Trametes versicolor), cheap fungal biomass (TTFB), was used for the adsorption of CR from aqueous medium. Batch studies conducted to study the effect of pH (2.0–10.0), agitation speed ...

In the modern era, dyes are inevitable and their surging usage leads to colossal contamination of aqueous streams, thereby threatening both the land and aquatic species. One among such dye is anionic Reactive Red 195 (RR 195), and traceable even at minute concentrations of aqueous streams, posing a severe threat to living species. Moreover, RR 195 is highly recalcitrant offering resistance to biodegradation due to the presence of an azo (-N=N-) group within its structure. Thus, there is a definite need to address the issue of eliminating RR 195 from industrial wastewater effluents. In lieu of this, the primitive objective of this study is to test the effectiveness of the natural adsorbent lotus leaf (

Aminated avocado seed powder (AASP)-an eco-friendly novel adsorbent has been used for the removal of Acid Yellow 17 (AY 17) and Amaranth (AMR) from an aqueous phase. The AASP (before and after adsorption) was systematically characterized by different analytical techniques such as FT-IR, FESEM, EDX, and N

The protonated amine modified-lotus stem powder (PAM-LSP) can be used to eliminate Reactive Red 120 (RR-120) from an aqueous solution as a potential adsorbent. Different operating variables like pH, agitation speed, adsorbent dosage, contact time, temperature, and initial RR-120 concentration were highly dependent on the adsorption process. FE-SEM (morphological), EDX (elemental), FTIR (functional), and N2 adsorption/desorption isotherms (texture properties) have been conducted to detect the adsorptive characteristics of LSP and PAM-LSP. To analyze the equilibrium data, non-linear isothermal models of Langmuir, Temkin, D-R (Dubinin-Radushkevich), and Freundlich were used. Among the four isothermal models, as shown by lower χ2 value (19.85), higher R2 (0.9956), the Langmuir matches the experimental data better than others. The experimental data were examined using non-linearized kinetic models of PFO (pseudo-first-order) and PSO (pseudo-second-order) and were better represented in the PSO model (R2 > 0.9902). It is noticeable that the adsorption of the RR-120 on PAM-LSP was a feasible, spontaneous, and endothermic physisorption process based on the calculated thermodynamic parameters like ΔHo (10.07 kJ/mol), ΔSo (33.8 J/mol K), ΔGo (-0.0539 to −1.3816 kJ/mol), Ea (5.9 kJ/mol), and S* (0.0043). Desorption experiments were performed with some selected eluents and the best desorbing eluent was found between NaOH, NaHCO3, NaCl, HCl, HNO3, CH3COOH, and DIW. The PAM-LSP was used without significant adsorptive performance loss for five adsorption/desorption cycles. Electrostatic interactions between the RR-120 dye molecules and the PAM-LSP are responsible for the primary adsorption mechanism. To remove RR-120 from wastewater, the eco-friendly prepared PAM-LSP was considered a highly recyclable and efficient adsorbent.

Due to the increasing number of natural and man-made disasters, mass casualty incidents occur more often than ever before. As a result, health care providers need to adapt in order to cope with the overwhelming patient surge. To ensure quality and safety in health care, accurate information in pandemic disease control, death reduction, and health quality promotion should be highlighted. However, obtaining precise information in real time is an enormous challenge to all researchers of the field. In this paper, innovative strategies are presented to develop a sound information network using the concept of "witness sensors." To overcome the reliability and quality limitations of information obtained through social media, researchers must focus on developing solutions that secure the authenticity of social media messages, especially for matters related to health. To address this challenge, we introduce a novel concept based on the two elements of "witness" and "sensor." Witness sensors can be key players designated to minimize limitations to quality of information and to distinguish fact from fiction during critical events. In order to enhance health communication practices and deliver valid information to end users, the education and management of witness sensors should be further investigated, especially for implementation during mass casualty incidents and epidemic outbreaks.
