For decades, a vast array of innovative biosorbents have been found out and used in the
removal of heavy metals, including bacteria, algae and fungi, etc. Although extensive …

The increasing use of heavy metals, synthetic dyes and pesticides is a major environmental
concern. Wastewaters containing heavy metals and dyes, extensively released from small …

The biosorption process has been established as characteristics of dead biomasses of both
cellulosic and microbial origin to bind metal ion pollutants from aqueous suspension. The …

This paper investigates the adsorption performance of spent tea leaves (STL) modified with
polyethylenimine (PEI) on two anionic dyes, namely Reactive Black 5 (RB5) and Methyl …

Heavy metals released from industrial activities pose a significant threat to the environment
and public health due to their reported toxicity even at trace levels. Although there are …

Carboxymethyl cellulose/polyethylenimine hydrogel (CMC/PEI) was firstly prepared with a
facile one-step method to enhance Cr (VI) removal. The sufficient hydrogen ions in double …

Due to its low cost, over the past decades, biosorption technology has been extensively
carried out to treat heavy metal-laden wastewater using biosorbents. Recent studies on …

A vast array of biological materials, especially bacteria, algae, yeasts and fungi have
received increasing attention for heavy metal removal and recovery due to their good …

Biosorption is a technique that can be used for the removal of pollutants from waters,
especially those that are not easily biodegradable such as metals and dyes. A variety of …

An adsorbent hydrochar was synthesized from corn cobs and modified with polyethylene
imine (PEI). The hydrochars before and after modification were characterized by scanning …
