Nitrogen compounds like ammonia and nitrite can antagonistically affect the environment human health in many ways. The high rise demand for food has led to excessive use of fertilisers eventually causing increased losses reactive nitrogen environment. Ammonia be introduced into through agricultural runoff, wastewater discharges other anthropogenic activities. over-accumulation different forms (ammonia nitrite) ecosystem noxious life including humans aquatic life. High concentrations both nitrogenous nutrient pollution, decreased oxygen levels water bodies ultimately resulting dead zones eutrophication. In elevated cause methemoglobinemia. Remediation these contaminants become a crucial environmental concern recent past. To prevent pollution reduce their harmful effects several mechanisms physical chemical treatments have been it is also required fix remaining pollutants by biological agents. Current review deals with mechanism, organisms, enzymes involved transformation fixation various (fixation using chemicals, modified biochar, solidification, phytostabilisation, nano material-related compounds, etc.)

Highly Efficient Recovery of Phosphate from Water Using Cerium Carbonate Hydroxide-Decorated Magnetic Biochar: A Slow-Release Phosphate Fertilizer for Agricultural Reuse

ACS ES&T Engineering, Год журнала: 2024, Номер unknown

Опубликована: Окт. 9, 2024

Phosphate removal plays a pivotal role in alleviating eutrophication and maintaining water quality. Cerium (Ce) demonstrates considerable promise phosphate removal, attributed to its strong affinity for ions. This study provides dual utilization strategy synthesizing Fe2O3- CeCO3OH-decorated hydrophilic porous biochar (Fe/Ce@HPBC), designed recovery from eutrophic waters followed by application as slow-release fertilizer. Fe/Ce@HPBC possessed excellent adsorption quantity, achieving maximum uptake of 203.88 mg/g accordance with the Sips model. Furthermore, experiment demonstrated that used fertilizer after could sustainably release 39.8% content within 28 days. Fe/Ce@HPBC-P also significantly increase effective phosphorus soil 65.51% promote maize seedlings 70.36%. Mechanistic investigation revealed outstanding was formation inner-sphere complexation through ligand exchange between Ce(HCO3)2+/Ce–OH, addition electrostatic attraction caused enhanced surface protonation. Overall, this contributes advancement techniques promotes development sustainable agriculture presenting an mitigating eutrophication.

Enhancement of the comprehensive performance of tetracycline adsorption by halloysite nanotubes: Kinetics, mechanism, and reusability study

Desalination and Water Treatment, Год журнала: 2024, Номер 320, С. 100695 - 100695

Опубликована: Авг. 8, 2024

One of the most widely produced and used antibiotics worldwide is tetracycline (TC). If these substances enter home sewer systems, water pollution can occur. This study aims to evaluate a novel nano-adsorbent for removal from aquatic environments. In this study, collective laboratory-scale tests were performed. Research has been conducted on factors, including temperature, contact time, pH, initial antibiotic concentration. addition, adsorption kinetics adsorbent have investigated. According results, it was shown that best adsorption, or 90 mg g −1 , occurred at 55 °C after 240 min contact. results research isotherms show Redlich-Peterson model pseudo-second order are followed in process. The efficiency process remained almost constant throughout three desorption cycles. option removing due its exceptional capacity ease separation unique properties. • Tetracycline halloysite nanotubes examined. Adsorption . Desorption examined various pH. Mechanism involves electrostatic hydrophobic interactions.
