Access to drinkable water is becoming more and more challenging due to worldwide
pollution and the cost of water treatments. Water and wastewater treatment by adsorption on …

The review aimed to identify differences and similarities in the adsorption process of five azo
dyes [congo red (CR), reactive black 5 (RB5), methyl orange (MO), orange II (OII), and …

Beef consumption produces a lot of bone waste. Here, We prepared Bali cow bones-based
hydrochar material (BCBHP) using the hydrothermal carbonization (HTC) method. The …

In this study, Delonix regia seed pods (DRSPs) as a locally available material were refluxed
in 90% H2SO4 to yield a novel D. regia seed pods biochar-sulfur oxide (DRB-SO). FTIR …

The presence of dyes in water stream is a major environmental problem that affects aquatic
and human life negatively. Therefore, it is essential to remove dye from wastewater before its …

In this study, biocarbon was obtained from the waste material corn digest. Carbon
adsorbents were obtained by physical activation of the precursor with CO2. Detailed …

In this study, the adsorption of methyl red (MR) dye from wastewater on nickel oxide (NiO)
doped in porous carbon derived from Hyphaene thebaica (HT) seeds (NiO@ HT derived C) …

This study demonstrates the feasibility of Algerian native pine tree bark (NPTB) as a low-
cost, sustainable adsorbent for methylene blue (MB) dye removal from wastewater …

The releasing of wastewater contaminated with direct red 28 (DR28) dye into receiving
water is a concern because it is a polyaromatic structure with difficult biodegradation. It …

Polyacrylic Acid grafted Agar-agar (AAc-graf-Agar), and polyacrylamide grafted Agar-Agar
(AAm-graf-Agar) have been synthesised by free radical polymerisation route initiated by …
