“…As seen in the figure, a period of 60 minutes was found to be sufficient for removal of Cu(II) with almond shell. Some of the previous researches similarly reported 60 minutes contact time for heavy metal removal with almond shell [15]; in other studies lower [16,17] and higher [14,18] contact times were also reported.…”

Abstract:In the work, adsorption of Cu 2+ ions onto almond shell were investigated under different operational conditions. Almond shell was used without any pretreatment prior to the tests. The optimum conditions for adsorption of Cu 2+ ions through almond shell were determined to be; pH 5.0, temperature 20ºC, shaking rate 125 rpm, sorbent dose 0.3 g and initial Cu 2+ ion concentration 50 mg/dm 3 . The equilibrium duration of the system was 60 minutes. The sorption capacities of the sorbents were predicted with the aid of equilibrium and kinetic models. The interactions of peanut shell with metal ions were constituted by SEM, EDX, FT-IR, XRD and AFM. The pseudo-first-order, pseudo-second-order, Weber-Morris, Elovich model and Bangham kinetic models were applied to test the experimental data. The Cu +2 ions adsorption onto almond shell was better defined by the pseudo-second-order kinetic model, for initial pH. The equilibrium data were evaluated using Langmuir, Freundlich, Temkin, D-R and Harkins Jura isotherms. The highest R 2 value in isotherm studies was obtained from Langmiur isotherm (R 2 = 0.98) for the inlet concentration.

“…The peaks at 2916 cm -1 and 2924 cm -1 are attributed to the symmetric and asymmetric C-H stretching vibration of aliphatic acids. The peak observed around at 1630 cm -1 is the stretching vibration of bond due to non-ionic carboxyl groups (-COOH, -COOCH 3 ), and may be assigned to carboxylic acids [29][30] .…”

“…Activated carbon is used widely for the adsorption of noxious gases and heavy metals, as well as for wastewater treatment because of its large adsorption capacity, large surface area, and high porosity [16][17][18][19][20][21][22][23][24][25]. On the other hand, the price of commercial activated carbon produced from bituminous coal, coconut shell, wood, or peat is relatively high because of the costly raw materials and expensive activation process [26].…”

As a replacement for activated carbon, biochar was synthesized and used for the adsorptive removal of formaldehyde and nitrogen oxide. Biochar was produced from the fast pyrolysis of the red marine macro alga, Pyropia tenera. The P. tenera char was then activated with steam, ammonia and KOH to alter its characteristics. The adsorption of formaldehyde, which is one of the main indoor air pollutants, onto the seaweed char was performed using 1-ppm formaldehyde and the char was activated using a range of methods. The char activated with both the KOH and ammonia treatments showed the highest adsorptive removal efficiency, followed by KOH-treated char, ammonia-treated char, steam-treated char, and non-activated char. The removal of 1000-ppm NO over untreated char, KOH-treated char, and activated carbon was also tested. While the untreated char exhibited little activity, the KOH-treated char removed 80% of the NO at 50°C, which was an even higher NO removal efficiency than that achieved by activated carbon.
