1 day ago · Toxic Congo Red (CR) dye in aqueous solution was removed by biosynthesized Selenium Nanoparticles from Prunus armeniaca L. (PAL-SeNPs) leaf wastes using green synthesis method and maximum adsorption capacity was calculated as 96.59 mgCR/gPAL-SeNPs at neutral pH.
1 day ago · For example, when using rice husk biochar, higher initial dye concentrations of Basic Blue 41 (BB41) and Basic Red 09 (BR09) resulted in lower percentage removal of cationic dyes. This can be attributed to the saturation of active sites on the biochar surface and the penetration of dye molecules into the biochar's pores . According to Güzel et ...
2 days ago · As a typical azo dye, Congo red has the advantages of high stability, low production cost and strong dyeing ability, and is widely used in textile, paper making, leather and other industries. Dye wastewater containing Congo red has the characteristics of high chroma, high chemical oxygen demand and high toxicity, which has caused great harm to human health and ecological environment [6] , [7] , [8] .

1 day ago · The secondary structure alteration of human serum albumin (α helical structure to cross β conformation) induced by 140 µM P 4R was evaluated utilizing far-UV CD spectroscopy. A red shift in the absorption maxima of the Congo red spectra further establishes the formation of β-rich aggregates of HSA.
2 days ago · Due to the synergistic effects of π–π stacking, hydrogen bonding and electrostatic attraction, the N, P-CDs exhibit an ultra-high adsorption capacity (3118.87 mg g −1) and a removal efficiency (97.4%, at 500 mg L −1) for CR, and also display excellent selective adsorption in both single-dye and dual-dye systems. This method offers a rational strategy for synthesizing novel CDs-based adsorbents for CR, which provides a demonstration for future dye adsorption studies and practical ...
