This paper presents the feasibility of removal of basic dye Rhodamine-B from aqueous solutions by using a low cost natural adsorbent perlite. Batch adsorption experiments were carried out as a function of pH, contact time, initial concentration of the adsorbate, adsorbent dosage and temperature. Dye adsorption equilibrium was rapidly attained after 50 minutes of the contact time, and it was des...

The usage of wastes of bagasse would be admirable from environmental and solid waste management point of view. Thus, herein, this data set present a facile method for providing an adsorbent from mixture of bagasse-bentonite. The prepared adsorbent was applied to remove Pb2+ from aqueous solution. It was conducted in laboratory scale using completely randomized design with variations in mixed ma...

Herein, dithiocarbamate-modified biochar (BC-HDTC) was successfully synthesized with nitric acid (HNO3), thionyl chloride (SOCl2), branched PEI and carbon disulfide (CS2). The effective anchoring of amine dithiocarbamate groups onto the surface proven by SEM, FTIR, XPS, N2 adsorption–desorption experiment. batch experiments demonstrated BC-HDTC can selectively remove 98% Pb(II) within multi-met...

This research work investigates the efficiency of H3PO4and KOH impregnated jackfruit leaf powder based carbon as adsorbent to remove Ni from wastewater. The removal characteristics of Nickel using both the adsorbents were investigated under various operating variables like contact time, adsorbent dosage, initial metal concentration, solution pH, temperature and stirring speed. The results showe...

Seedlings of aubergine (Solanum melongena L.) cv. ‘Rima’ were used as scion (R) and control (non-grafted) and rootstock (self-grafted) (RR), while two hybrid tomatoes ‘Heman’ (Lycopersicon hirsutm) and ‘Primavera’ (Lycopersicon esculentum) were used as rootstocks. Grafted and non-grafted plants were grown in the greenhouse and in the open-field. Grafted plants Rima and Heman (RH) were more vigo...

In this study, the hydrogel was prepared by dissolving and regenerating poplar cellulose in NaOH/urea/water system. The TEMPO-oxidized hydrogels (TCH) were using microwave-assisted accelerated TEMPO-oxidation Polyethyleneimine (PEI) grafted onto TCH with glutaraldehyde as a cross-linking agent products named TCP. characterized SEM, FTIR, XPS, elemental analyzer. maximum adsorption capacities of...

Abstract This study investigates the potential of a hybrid process combining sand filtration column with activated banana peels macrocomposite (ABPM) adsorbent for river water treatment. Scanning electron microscopy (SEM) analysis displayed an irregular structure and high cavities peel surface that caters to deposition contaminants, while energy-dispersive X-ray detected major elements adsorben...

Nickel has several industrial uses and is a valuable metal, making its selective separation recycling priority goal. A novel adsorbent, Schiff base organically modified silica (ORMOSIL) aerogel, was prepared, for nickel removal from wastewater with other metal ions, by including salen ionophore in the silica-based network. The newly developed adsorbent takes advantage of salen’s selectivity hig...

Calcium alginate beads doped with hydrazine sulphate-treated red mud are investigated as adsorbent for extracting lead ions from water using batch methods of extraction. Different extraction conditions are optimised for maximum lead extraction. Substantial amount of lead is removed, and the adsorption ability is found to be 138.6 mg/g. Surface characterization using FTIR, EDX, and FESEM confirm...

The objective of this research was to seek a cost effective solution to prepare adsorbents for nitrogen oxide from surplus sludge. Leaf litter and powder coal ash were used as cheap and easily available additives. An adsorbent for nitrogen oxide was prepared by pyrolysis of dried sludge mixed with zinc chloride. Under optimum pyrolysis conditions of 375°C for 90 min and a zinc chloride content ...
