This study aimed at optimizing the hexavalent chromium (Cr (VI)) removal from aqueous
solution by a new cassava sludge-based activated carbon (CSAC) using response surface …

The present paper discusses response surface methodology (RSM) as an efficient approach
for predictive model building and optimization of chromium adsorption on developed …

Recently, rapid industrialization leads to excessive release of heavy metals such as Cr (VI)
in the environment. Exposure to chromium (VI) can cause kidney and liver damage …

Because of its acute toxicity and high mobility, the hexavalent chromium [Cr (VI)] found in
wastewater is a risk to the environment. In this study, activated carbon was produced from …

The reusability of adsorbents for Cr (VI) removal and the related mechanism are important to
practical application. In this study, commercial activated carbon (AC), sludge-derived …

In this study, a response surface methodology (RSM) approach using central composite
design (CCD) was investigated to develop a mathematical model and to optimize the effects …

A hexavalent form of chromium, which is a major pollutant found in water bodies, has lethal
impacts on aquatic life and human beings. Among various effluent treatment techniques, the …

In this study, unmodified biosorbent was obtained from Arachis hypogea husk and applied to
remove hexavalent chromium [Cr (VI)] from aqueous media through batch technique. The …

An adsorbent prepared from sugarcane bagasse with chemical activation by zinc chloride
was used to study its sorption potential on removing chromium (VI). In this work the …

Hexavalent chromium is one of the contaminants recognized as a carcinogenic and
mutagenic agent. Therefore, it is essential to remove it from wastewater before disposal. In …
