TL;DR: Experimental results show that the BET surface area of activated carbons irrespective of the activation agent resulted in surface area in excess of 2000 m(2)/g, while the yield of the activated carbon compares well with the conventional heating methods.

TL;DR: In this article, a series of experiments have been conducted to study the effects of different carbonization temperatures (400, 600, 800 and 1000°C) on characteristics of porosity in carbonized coconut shell char and activated carbon derived from carbonized coconuts with different activation times (30, 60, 90 and 120 min) at activation temperature of 900°C.

TL;DR: In this article, the effect of microwave radiation time and K2CO3/C ratio on the yield and adsorption capacities of activated carbons was evaluated, and the results indicated that the optimum conditions were as follow: microwave power 700 W, microwave radiation 30 min; K 2CO3 /C ratio 1.5:1.

TL;DR: In this paper, textural characterization of an activated carbon derived from carbonized coconut shell char obtained at carbonization temperature of 600°C for 2h by CO2 activation was investigated, and the effects of activation temperature, activation time and flow rate of CO2 on the surface area, total volume, micropore volume and yield of activated carbons prepared were evaluated systematically.

TL;DR: In this article, a novel hybrid material was fabricated using mercaptoamine-functionalised silica-coated magnetic nanoparticles (MAF-SCMNPs) and was effective in the extraction and recovery of mercury and lead ions from wastewater.
