In this research work, an ecofriendly approach was adopted for the treatment of two abundant liquid and solid agricultural wastes generated by olive mill industry: wastewater (OMWW) raw pomace (ROP). It consists, firstly impregnation ROP OMWW conversion resulting impregnated sample (IROP) into hydrochars biochars through hydrothermal carbonization (HTC) slow pyrolysis methods, respectively. The...

Thermal treatment is simple and has high potential in activated carbon (AC) modification because its functional groups, structures, pores can be significantly modified. However, the changes characteristics of ACs, affecting catalytic activity, have not been investigated enough. Therefore, this study, a coal-based powdered AC (PAC) was thermally treated, characterized, subjected to removal an an...

In this study, activated carbons derived from walnut shells (CA-N) and apple wood (CA-M) were used as adsorbents to remove cobalt(II) strontium(II) ions aqueous solutions. The novel materials obtained using nitric acid (CA-Mox) acid/urea mixture (CA-Mox-u, CA-Nox-u) oxidizing agents. physical–chemical characteristics of determined nitrogen sorption isotherms, SEM-EDX, FTIR, pH metric titrations...

<p>In the present study, adsorption experiments were carried out to investigate removal of rhodamine B from an aqueous solution using chemically activated carbon corn cobs, a cheaper adsorbent. The characteristics determined X-ray diffraction, SEM, iodine number, pHpzc, and Boehm titration method. results show that prepared is amorphous, microporous, generally acidic on surface. kinetic s...

Granular activated carbon (GAC) was synthesized from Silver berry (Elaeagnus Angustifolia L.) seeds using zinc chloride as the activation agent. To optimize operating parameters, effects of time and temperature carbonization, impregnation ratio, heating rate on iodine number yield were studied. Optimized parameters ratio 1:1, carbonization 500 °C, 1 hour, 5 °C/min. The GAC under optimized condi...

To improve water vapor adsorption, this study employed oxalic acid–ethyl acetate acidic hydrolysis to modify honeycomb activated carbon and introduce hydrophilic functional groups. Scanning electron microscopy (SEM), Boehm titration, Fourier transform infrared spectroscopy (FT-IR), an automatic surface area analyzer (BET) were used characterize the microscopic morphology, groups, specific area,...

Abstract Nanostructured bio-adsorbents were prepared by physical or chemical activation of the residue supercritical extraction raspberry seed. Their physicochemical properties determined elemental analysis, low-temperature nitrogen adsorption/desorption, Boehm titration and scanning electron microscopy. The biocarbon obtained as a result precursor showed basic character surface its S BET was 7...
