in this work, removal of c. i. acid red 14 was investigated by pumice stone as a low cost adsorbent. various parameters such as initial dye solution, contact time and ph were studied. removal of dye were increased by increasing of contact time and initial dye solution and deceased by increasing of ph. three isotherm models were studied. linear and non-linear regression analyses were used for de...

Mineral profile and some selected components of three cultivars of onion (Allium cepa L.) (Dan Zaria, red creole and white creole) bulb were compared with garlic (Allium sativum L.) clove. This was pertinent to establish their potentials in ensuring adequate nutrition and food security. Simultaneous multi-element analysis was done by inductively coupled plasma-optical emission spectroscopy (ICP...

Purpose This study aims to demonstrate that orange-derived and lemon-derived systems can be used in continuous processes as efficient adsorbents the entrapment of some anionic cationic dyes textile dyeing wastewater effluents. Design/methodology/approach Physically chemically modified orange lemon mesocarps are natural for Basic Blue 3, Yellow 21, Red 18 Green 4 Acid 264, 49 337, all commonly i...

An economic low-temperature self-ignition solution combustion method was used to synthesize 1–11 mol% chromium ion (Cr 3+ ) doped MgAl 2 O 4 nanoparticles (NPs). The structural, morphological and energy gap variations due the influence of Cr on host matrix were evidenced by powder X-ray diffraction (PXRD), Fourier transformed infrared spectroscopy (FTIR), diffuse reflectance (DRS), transmission...

SBA-15 grafted with N-(4-(trimethylsilyl) butyl)-9H-fluorene-9-amine was synthesized by a simplestrategy and applied to removal of Acid Red 33 and Acid Black 194 from aqueous solutions. SBA-15 was synthesized and Functionalized according to procedure in the literature. Fluorenefunctionalized SBA-15 was showed the BET surface area 200 m2g-1 and pore diameter 4.2 nm,based on adsorption-desorption...
