In the present work, the usefulness of almond peel as a sorbent material has been investigated for the removal of methylene blue from synthetic aqueous solutions in batch conditions. Isotherm of dye sorption was measured. The influence of different experimental parameters such as: almond peel mass, particles size, temperature, initial pH of solution and NaCl concentration on this isotherm was s...

The potential use of Croatian natural zeolite clinoptilolite as alternative adsorbents for removal of enrofloxacin (ENRO) as model pollutant was studied in a batch system. The influence of contact time and initial ENRO concentration on the sorption process was investigated. The percentage removal of ENRO from aqueous phase decreased with an increase in initial concentration. The experimental da...

In the present study, activated carbons of Eichornea crasssipes(EC), Sugarcane bagassae(SB), Tea waste(TW) and Guava leaf(GL) were prepared from agricultural wastes and used as an adsorbents for the removal of Acid Blue 92 (AB92) dye from aqueous solution. The effects of pH, adsorbent dosage, initial dye concentration and contact time on the extent removal of AB92 has been studied by Batch adso...

Present study dealt the removal of Cr(VI) in a tannery industry wastewater using rice husk silica powder as an adsorbent.The experimental investigations have been carried out by using rice husk silica powder for different adsorption dosage, different contact time and different pH against the initial Cr(VI) concentration of 292 mg/L. The maximum percentage removal of Cr(VI) in a tannery industri...

Chemically modified kenaf core fibres were prepared via esterification in the presence of citric acid (CA). The adsorption kinetics and isotherm studies were carried out under different conditions to examine the adsorption efficiency of CA-treated kenaf core fibres towards methylene blue (MB). The adsorption capacity of the kenaf core fibres increased significantly after the citric acid treatme...

A glass fiber cloth (GFC) with microporosity was prepared upon the suppression of crack generations. After GFC heat-treated, it slowly cooled to room temperature and then subsequently treated hydrochloric acid. The experimental data through complementary techniques including scanning electron microscopy, nitrogen adsorption/desorption isotherm, solid-state 29Si nuclear magnetic resonance spectr...

The recovery and removal of the most organic acids in liquid solutions is usually treated with fixed-bed adsorption processes. Among many adsorbents, Granular Activated Carbon (GAC) is used to remove organic pollutants such as Benzoic Acid (BA) from wastewaters conventionally. In this research, adsorption isotherm curves of BA onto GAC at varying temperatures 25-60 °C are developed and the ...

Municipal solid waste used for landfill becomes stabilized, or aged, some years after placement, and can be safely excavated; the term 'mineralized refuse' is used in this study. The adsorptions of phosphorus, and the nitrification of the mineralized refuse and clay, were investigated by batch incubation. The variation of phosphorus adsorption in the mineralized refuse was fitted to the Freundl...

In this study, the adsorption behavior of anionic dyes from aqueous solution onto mesoporous carbon material (CMK-1) and modified with polymer (PANI/CMK-1) has been investigated as a function of parameters such as adsorbent dose (0.08-0.8 g/L), solution pH 3–10, contact time and initial concentration (10-100 mg/L). The influence of these parameters on the adsorption capacity has been studied us...

Condensate porosity in porous materials has a significant influence on comfort, energy consumption, and material’s strength durability. The variation of the moisture content material for given relative humidity describes storage capacity to be determined experimentally through water sorption isotherm. However, characterisation isotherm is very time-consuming, mostly high conditions, which may c...
