Biosorption is considered to be one of the favourable remediation techniques for fluoride
removal from aqueous solutions. Other conventional techniques such as precipitation …

Equilibrium adsorption of aniline, benzaldehyde, and benzoic acid on granular activated
carbon (GAC) has been investigated. Experiments were carried out on two sizes of activated …

The present paper aims to develop a low cost, efficient and environment-friendly process by
the use of an agro-industrial waste to purify dye-contaminated aqueous solutions. The ability …

Increased urbanisation and industrialisation has led to a situation of higher quantities of lead
in waste water which has become a serious problem. Lead is toxic and is not essential for …

A new biochar was produced from mandarin peel residues and its ability to remove Acid
Red 35 (AR35) dye from wastewater was investigated. The production was achieved by …

Adsorption and desorption of nitrogen (N), phosphorus (P), and potassium (K) soils are
controlled by pH, pH buffering capacity, organic matter, and cation exchange capacity …

Novel anion exchangers were prepared from pine (Pinus sylvestris) sawdust and bark,
spruce (Picea abies) bark, birch (Betula pubescens/Betula verrucosa) bark and peat for the …

A novel composite basing on the Fe 3 O 4 nanoparticle, the graphite oxide nanosheet
(GON), and the citric acid-crosslinked β-cyclodextrin polymer (CA-CDP) was prepared for …

The deteriorating state of soil fertility and low agricultural productivity in Ethiopia can be
traced to the lack of equivalent consideration given to the soil's biological, chemical, and …

Orange peel waste is generally of low economic value even though it contains components
such as cellulose which can be utilised to produce nanocellulose adsorbents for wastewater …
