Simultaneous removal of $${\text{Cr}}^{3+}$$ and acidic dye from model tannery wastewater was investigated using local nano-clay modified by 3-chloro-2-hydroxypropyltrimethylammonium chloride surfactant. X-ray fluorescence, Fourier-transform infrared spectroscopy, diffraction, scanning electron microscopy, carbon, hydrogen, nitrogen sulfur analysis, Brunauer–Emmet–Teller analysis pH zero-point ...

In this study, the adsorption of thallium (III) ion from aqueous solutions onto modified ZnOnanopowder as a fairly low cost adsorbent has been investigated in batch mode. It was found thatmodification of the adsorbent was essential for obtaining the significant adsorption percentage. Theadsorbent modified by sodium phosphate solution. The effect of experimental parameters such asinitial pH of s...

The properties of blends of banana, potato, and rice starches were studied to assess their suitability as an alternate for chemically modified starches. The blends of banana, potato, and rice starches were prepared in the respective ratio of 1:3:2, 3:2:1, and 2:1:3. The blend with higher proportion of banana and rice starches (BPR213) showed highest water absorption capacity and oil absorption ...

Vibration behavior of different types of porous functionally graded (FG) conical sandwich shells are investigated based on a modified high order sandwich shells theory for the first time. Sandwich shell includes FG face sheets covering a homogeneous core and the second one includes homogeneous face sheets and a FG core. Power law rule modified by considering two types of porosity distributions ...

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...

In the present study, Juglans regia shells were used to prepare activated carbon by acid treatment method. J. regia shell-based activated carbon was used for the adsorption of two synthetic dyes namely, a basic dye malachite green and an acid dye amido black 10B. The prepared adsorbent was crushed and sieved to three different mesh sizes 100, 600 and 1,000 lm. The adsorbent was characterized by...

This paper reports the evaluation of adsorbing Cr (VI) ions on sorbent prepared from chitosan (CHT), a versatile derivative of chitin, and dodecyl amine modified locally available kaolinite clay (Bijoypur clay) (MC) that has excellent mechanical properties and great resistance to chemical and biological attack. The effect of the initial metal ion concentration, solution pH, contact time, and ad...
