Abstract Locally available apricot ( Prunus armeniaca L.) seed shell wastes were utilized for the preparation of an efficient dye biosorbent. The as-prepared powder ASP ) was thoroughly characterized using FTIR, SEM-EDX, XRD, BET surface area, and pH PZC measurements to elucidate its functional groups, as well texture morphology charge. effect several process variables (such contact time, bioso...

The ability of waste banana pith to remove Congo red from aqueous solution was investigated. Various parameters such as initial dye concentration, contact time, adsorbent dosage and pH effect were studied. The adsorption rate constant was found to be 1 X 10. min'} at 50 mg I-I dye concentration. Above 92% removal was observed in the pH range 2-11. The removal of dye by banana pith is mostly due...

Micropropagation of banana (Musa paradisiaca Linn.) var Grand naine was carried out with media sterilized by microwave radiation. Microwave oven was effectively used to sterilize the media for in vitro shoot-multiplication of banana against autoclave. Sterilization of media in microwave oven was successfully achieved at 900W/200 ml media (4 min). In vitro shoot-multiplication was higher in the ...

in this study, mesoporous mcm-41 has been modified by incorporation of aluminum ion asa rapid, simple and inexpensive method for modification. the adsorbent is characterized usingpowder x-ray diffraction and nitrogen adsorption-desorption isotherm data. the distributioncoefficient of cadmium ion on the mesoporous aluminosilicates has been enhanced with theincrease of the aluminum in the framewo...

In this paper, the adsorption of Basic Blue159 (BB159) onto banana peel as a low-cost material was studied. At first, the banana peel was sieved. Later, banana peel particles were characterized by field emission scanning electron microscopy (FESEM), energy dispersive x-ray spectroscopy (EDXS) and Fourier Transform Infrared (FTIR) techniques. Batch adsorption experiments were carried out as a fu...

Few studies have combined molecular- and macroscopic-scale investigations with surface complexation model (SCM) development to predict trace metal speciation and partitioning in aqueous systems over a broad range of conditions. In this work, an extensive collection of new macroscopic and spectroscopic data was used to assess the ability of the modified triple-layer model (TLM) to predict single...

The present study was undertaken to investigate the role of banana extract (BE) on synchronous plantlet formation from seeds of Dendrobium lituiflorum Lindl. The seedlings formed on modified Knudson C (KC) medium supplemented with 20% (v/v) BE had significantly high fresh and dry weights. Morphologically uniform plantlets with elongated leaves and well developed roots were formed on KC medium w...

Rhodamine B (Rh B) is a toxic dye that is harmful to the environment, humans, and animals, and thus the discharge of Rh B wastewater has become a critical concern. In the present study, reduced graphene oxide-supported nanoscale zero-valent iron (nZVI/rGO) was used to treat Rh B aqueous solutions. The nZVI/rGO composites were synthesized with the chemical deposition method and were characterize...
