Pichia kudriavzevii (JD2) Immobilized on Acid Activated Perlite as a Biosorbent for Solid Phase Extraction of Cr(III) Determination by AAS (Atomic Adsorption Spectroscopy)

Microscopy Research and Technique, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 11, 2025

In this study, the preconcentration of Cr(III) ion in Pichia kudriavzevii JD2 immobilized perlite adsorbent by solid phase extraction was investigated. The determination performed using flame atomic absorption spectrometry (AAS). effects pH, amount, recovery solution volume and type, sample flow rate on efficiency ions were Optimized conditions for established a column technique. optimal parameters determined as pH 4, 2 mol/L HNO3 with 10 mL, 1-3 mL/min, factor 25. Under these conditions, found to be 100.1% ± 0.3% 95% confidence level. Analytical variables limit detection (LOD) 4.8 μg/L quantification (LOQ) 15.8 ion. accuracy method standard reference materials (SPS-WW1). relative error less than 10%. applied various water samples, such tap mineral waters.

Adsorption of heavy metals onto food wastes: a review

Frontiers in Environmental Chemistry, Journal Year: 2025, Volume and Issue: 6

Published: April 14, 2025

There has been an increase in the production of food waste materials worldwide due to rapid population growth. The ineffective and sometimes unscientific ad hoc disposal these led environmental pollution. Studies have reported occurrence heavy metals water resources poses serious health threats environment human health. Heavy are documented be recalcitrant conventional treatment facilities since they non-biodegradable. use waste-based adsorbents provides alternative solution for adsorption resources, with concomitant benefit valorization otherwise materials. Therefore, this study examined applications removal metal ions. adopted a literature-based approach which involved reviewing published papers from selected science databases. results indicate that bioadsorbents great efficiencies different with, rice husks sugarcane bagasse demonstrating special sorption properties, especially chromium lead ions, respectively. data were mostly best described by Langmuir Freundlich isotherm models, suggesting monolayer coverage similar sites heterogeneous surface, Further, kinetic studies indicated processes largely followed pseudo second-order model, showing chemisorption-mediated rate-limiting steps. However, regardless encouraging attained, limitations such as variation composition structure. This leads inconsistencies efficiencies, regenerations reuse, reduced capacities. is also possibility leaching may in-turn cause secondary Sustainability investigations life cycle assessment, cost-benefit analysis, pilot-scale optimization present areas future research.

Application of fertigation using biotreated agro-industrial wastewater (with Bacillus paramycoides MT477810) on the growth of two vegetables Capsicum annuum (var. Astra) and Lycopersicon esculentum (var. Kristina)

Water Practice & Technology, Journal Year: 2024, Volume and Issue: 20(1), P. 108 - 126

Published: Dec. 18, 2024

ABSTRACT This research explored the use of fertigation technique with treated agro-industrial wastewater to enhance growth Capsicum annuum (var. Astra) and Lycopersicon esculentum Kristina). The wastewater, collected from Bajwa Agro Industries in Lahore, was biotreated using bacterial strain Bacillus paramycoides MT477810, a 10% inoculum incubated at 37 °C for 48 h. achieved an 87% decolorization wastewater. Physicochemical analysis before after biotreatment showed reductions pH (60%), EC (22%), salinity (16%), turbidity (48%), COD (40%), BOD (73%), TDS (62%), TSS (25%). two vegetable varieties were fertigated both untreated assess their effects on seed germination plant growth. Results indicated significant reduction phytotoxicity (over 50%) plants grown Additionally, irrigated 9–30% increase fresh dry weights compared those Nutritional revealed that crops had 12–48% higher nutrient content. These findings emphasize effectiveness biological treatment reducing pollutants enhancing availability crops.
