Crystal violet dye, widely used in industries, poses environmental and human health hazards due to its persistence toxicity. Effective removal methods are critical mitigate these impacts. This study presents the synthesis of a novel ZrO2@MnCO3@CdCO3 nanocomposite for efficient crystal dye from aqueous solutions. The was synthesized using precipitation method characterized XRD, SEM, EDX, BET surface area analysis. Adsorption experiments were conducted under various conditions, including pH, contact time, concentration, temperature. exhibited mesoporous structure (22.38 m2/g area, 0.0935 cm3/g total pore volume, 8.79 nm average size) an crystallite size 76.30 nm. maximum adsorption capacity 179.52 mg/g, following pseudo-second-order kinetics Langmuir isotherm. Thermodynamic studies revealed exothermic, physical, spontaneous process. Regeneration demonstrated high reusability with desorption efficiency reaching 99.67% over five cycles.

Adsorption of Acid Yellow 36 and direct blue 86 dyes to Delonix regia biochar-sulphur

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Янв. 27, 2025

Abstract This study aims to investigate a new approach removing hazardous dyes like Direct Blue 86 (DB86) and Acid Yellow 36 (AY36) from aqueous environments. Delonix regia biochar-sulphur (DRB-S), made seed pods (DPSPs), is an inexpensive environmentally friendly adsorbent. Different characterization investigations using BJH, BET, FTIR, SEM, DSC, TGA, EDX were utilized in the descriptions of DRB-S biosorbent. The optimal pH for AY36 dye DB86 adsorption adsorvbent was at 1.5. For DRB-S, equilibrium attained 30 90 min reaction time interaction. Langmuir model (LGM) pseudo-second-order-model (PSOM) best describe biosorption both molecules biosorbent owing equal homogeneous spread over porous surface chemisorption process which involved valency force through exchange electrons between prepared determined capacities (AY36 DB86) found be 270.27 mg/g 36.23 mg/g, respectively. In conclusion, this recently synthesised adsorbent exhibited impressive sorption capacity successfully removed dyes. suggests that has potential applications wastewater treatment can recycled without affecting its effectiveness.

Aflatoxin B1 (AFB1) biodegradation by a lignolytic phenoloxidase of Trametes hirsuta

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Фев. 21, 2025

Abstract Aflatoxin B 1 (AFB ) is a highly potent mycotoxin that poses serious threat to human and animal health. This study investigated the biodegradation of AFB by supernatant submerged cultured Trametes hirsuta , with focus on identifying characterizing responsible enzyme(s). The extracellular enzymes white-rot mushroom were extracted from pre-separated using anion exchange fast protein liquid chromatography (FPLC). To pinpoint specific enzyme, eluted fractions exhibiting highest degradation activity subjected detailed biochemical proteomic analyses. A second purification step, ultrafiltration, yielded an electrophoretically pure enzyme. Sequencing tryptic peptides nano-LC system coupled qQTOF mass spectrometer identified enzyme as lignolytic phenoloxidase. exhibited molecular 55.6 kDa achieved impressive rate 77.9% under optimized experimental conditions. first fungal phenoloxidase capable aflatoxin without requiring hydrogen peroxide cofactor, highlighting its unique catalytic mechanism. It may be used in remediation strategies, such treating surfaces contaminated fruits, vegetables, nuts.
