The potential of using Typha Angustata L modified AC-MnO2-NC to eliminate the dyes namely Malachite Green and Reactive Red 4 dyes are studied. The result of more than a few parameters such as adsorbent dosage, contact time, temperature, the initial concentration of the adsorbate and pH has been evaluated. Tempkin, Halsey, Langmuir, Dubinin-Radushkevich and Freundlich isotherms are too studied. The lessons exposed that AC-MnO2-NC is appropriate to employ as an adsorbent to take away both Malachite Green and Reactive Red 4 dyes.

Withania somnifera (L.) Dunal commonly known as 'Ashwagandha' is a widely used herb in Ayurvedic medicine.In the present study, root extracts of Withania somnifera were analysed for phytochemical constituents, and antimicrobial property. Antibacterial activity of root extract was tested by agar-well diffusion method against Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa and Salmonella paratyphi B. The study also investigated the effect of temperature on its antibacterial activity. Qualitative phytochemical analysis revealed the presence of carbohydrates, reducing sugars, alkaloids, phytosterol, fixed oils, proteins, phenolic compounds and flavonoids. All the bacterial strains were found to be sensitive to acetone, ethyl acetate and ethanol extracts. Acetone and ethanol extracts were more effective against Klebsiella pneumoniae, whereas ethyl acetate extract was more effective against Pseudomonas aeruginosa and Salmonella paratyphi B. The effect of temperature on the antimicrobial potential of the root extracts of the plant remained reasonably unaffected. The present screening demonstrated that Withania somnifera root extract has potent antibacterial activity and a potential source of new class of antimicrobial compounds that could be useful for infectious disease chemotherapy and control.

For their unique physical, chemical and biological characteristics, silver nanoparticles (AgNPs) are used in a variety of applications in the sectors of health and wellness as well as consumer and industrial products. We describe here the production of silver nanoparticles (AgNPs) using activated carbon from locally accessible biowaste Caesalpinia pulcherrima pod is the goal of this work, which aims to characterise the activated carbons generated by oxidation of activated carbons of comparable porosity with Sulphuric acid, nitric acid, and phosphoric acid, respectively. Using Caesalpinia pulcherrima plant extract as a reducing agent, silver particles may be made. TEM was used to determine the particle size, distribution, shape, shape heterogeneity, and aggregation. Analysis of the silver nanoparticle's composition has been done using EDAX. According to the findings, activated carbon derived from Caesalpinia pulcherrima pod is ideal for the adsorption of textile dyes such as Eriofast Blue (EB) and Erionyl Orange (EO) and might be employed as a low-cost efficient adsorbent in the treatment of industrial wastewater.
