The industrialization development has delivered a number of anionic species (nitrate, nitrite,
cyanide, phosphate, perchlorate, and fluoride), as well as anionic metal complexes …

Perchlorate, which could not be easily degraded in the environment, is a persistent
inorganic pollutant in water with high water-solubility, diffusivity, and stability. Its pollution …

Two biochars, from Chinese cabbage (Cc, Brassica rapa pekinensis) and rape (Ra, Brassia
campestris L.), were used to prepare biochar/Mg-Al layered double oxides (LDOs) as …

In this work, magnetic lignin-based nanoparticles (M/ALFe) were developed and used to
adsorb phosphorus to obtain phosphorus-saturated nanoparticles (M/ALFeP). The …

Highlights•PG-PB biosorbent possesses high PFOA sorption capacity: 456.0 mg/g at pH

Abstract Perchlorate (ClO 4−) in water is an emerging contaminant that threatens human
health by inhibiting the uptake of iodine in the thyroid gland. Biopolymer adsorbents …

Conversion of the abundant agricultural residual cotton stalk (CS) into useful chemicals or
functional materials could alleviate the fossil fuels caused energy shortages and …

A magnetic biocomposite based bio-sorbent (corn straw) was prepared after in situ co-
precipitation with Fe2+ and Fe3+ solutions and amine functionalization. The characteristics …

A new quaternary ammonium anion exchanger derived from the cellulose-based biomaterial
(sugarcane bagasse) was prepared for phosphate adsorption and then the phosphate …

Ion exchange technology removes ionic compounds from waters effectively but treatment of
the spent regenerant is expensive. The bioregeneration of sulfate-laden strong base anion …
