Coffee residue, a low-cost agricultural byproduct, was tested as precursor for the production of porous carbons in chemical scheme using phosphoric acid and zinc chloride. The raw material impregnated with increasing impregnation ratio (mass ZnCl2 or H3PO4/mass coffee residue) from (0 to 100) % followed by pyrolysis at 600 °C 1 h. products were characterized adsorption N2 77 K proved be highly microporous high surface area. had strong influence on pore structure these activated carbons,...
The efficiency of date tree leaves as a low cost adsorbent for removing lead ions from aqueous solution has been investigated in this paper. Batch experiments were conducted to study the effects main parameters such contact time, initial concentration Pb(II), dose, pH, agitation speed, ionic strength, and temperature on adsorption Pb(II) by leaves. maximum removal lead(II) is found be 94 % at pH 5.8, 10 mg·L−1, dose 1 g·L−1, speed 200 rpm, strength 0.005 M, 25 °C. Dynamics process studied,...
Zeolite-supported TiO2 and Fe-doped TiO2/zeolite photocatalysts were synthesized, aiming at improving the adsorption properties of microporous support towards polluting dyes photocatalytic performance in treatment adsorbed organics. The TiO2/HY zeolite catalyst exhibited best degradation methylene blue, MB, over 10 wt% under UV light 254 nm. addition Fe species synthesis mixture led to Fe-TiO2/HY catalyst. combination adequate zeolite, good titanium dioxide dispersion, doping a remarkable...
This work investigates the possibility to use reed as an adsorbent for removal of basic yellow 28 (BY28), industrial textile dye from aqueous solution. Batch adsorption experiments at 258 °C and agitation speed 400 rpm were carried out effects operational parameters including contact time, initial concentration, dose, well solution pH on sorbed amount investigated discussed. The maximum uptake BY28 was about 140 mg/g it obtained pH6, concentration 100 mg/L, dose 0.5 g/L. It also established...
In the present study, three compositions of W-doped titania nano-photocatalyst are synthesized via sol–gel method. The powders obtained were characterized by X-ray diffraction, Raman spectroscopy and UV–visible diffuse reflectance spectroscopy. photocatalytic performances different photocatalysts tested with respect to degradation Diuron in water solutions under simulated solar light visible irradiation. W0.03Ti0.97O2 catalyst exhibits better photoactivity than pure TiO2 even light. This...
