Evaluation of Adsorption Efficiency on Pb(II) Ions Removal Using Alkali-Modified Hydrochar from Paulownia Leaves
(MDPI, 2023)
In this study, hydrothermal carbonization (HTC) at five temperatures (180, 200, 220, 240,
and 260 C) was applied to transform Paulownia leaves (PL) into a carbonaceous sorbent of Pb(II)
from aqueous solutions. To enhance ...
Food waste (beetroot and apple pomace) as sorbent for lead from aqueous solutions – alternative to landfill disposal
(MDPI, 2023)
This article presents studies, whose main goal was to minimize food waste. To achieve this goal, it is necessary to expand the scope of their application, for example, for the purification of polluted water from heavy ...
Hydrothermal Carbonization of Waste Biomass: A Review of Hydrochar Preparation and Environmental Application
(MDPI, 2024)
The concept of a bio-based economy has been adopted by many advanced countries around
the world, and thermochemical conversion of waste biomass is recognized as the most effective
approach to achieve this objective. ...
Ability of Deep Eutectic Solvent Modified Oat Straw for Cu(II), Zn(II), and Se(IV) Ions Removal
(MDPI, 2023)
In the proposed study, agro-waste biomass oat straw (OS) was considered a potential adsorbent for Cu(II), Zn(II), and Se(IV) removal from aqueous solutions. In order to obtain material with better adsorption abilities, the ...
Bentonite Modified with Surfactants—Efficient Adsorbents for the Removal of Non-Steroidal Anti-Inflammatory Drugs
(MDPI, 2024)
Organobentonites have been applied for the removal of two common non-steroidal anti-inflammatory drugs, ibuprofen (IBU) and diclofenac sodium (DS), from aqueous solutions. Two surfactants, one with and the other without ...
Efficient Removal of Water Soluble Fraction of Diesel Oil by Biochar Sorption Supported by Microbiological Degradation
(MDPI, 2024)
The contamination of the water bodies by diesel oil (DO) and its water-soluble fraction (WSF) represents one of the most challenging tasks in the management of polluted water streams. This paper contains data related to ...
Preparation and Characterization of the Sulfur-Impregnated Natural Zeolite Clinoptilolite for Hg(II) Removal from Aqueous Solutions
(MDPI, Basel, 2021)
Sulfur-impregnated zeolite has been obtained from the natural zeolite clinoptilolite by chemical modification with Na2S at 150 degrees C. The purpose of zeolite impregnation was to enhance the sorption of Hg(II) from aqueous ...
A Mechanism Assessment and Differences of Cadmium Adsorption on Raw and Alkali-Modified Agricultural Waste
(MDPI, Basel, 2022)
In this study, raw corn silk was considered for the removal of cadmium ions from aqueous solutions. In order to improve adsorption characteristics, the KOH treatment was applied as a route to obtain modified materials. ...
