Data from: Synthesis of activated carbon from biowaste of fir bark for methylene blue removal
Activated carbon (AC) was successfully prepared from low-cost forestry fir bark (FB) waste using KOH activation method. Morphology and texture properties of ACFB was studied by scanning and high-resolution transmission electron microscopies (SEM and HRTEM), respectively. The resulting of fir bark based activated carbon (ACFB) demonstrated high surface area (1552 m2/g) and pore volume (0.84 cm3/g), both of which reflect excellent potential adsorption properties of ACFB towards methylene blue (MB). The effect of various factors, such as pH, initial concentration, adsorbent content as well as adsorption duration were studied individually. Adsorption isotherms of MB were fitted using all three non-linear models (Freundlich, Langmuir and Tempkin). The best fitting of MB adsorption results was obtained using Freundlich and Temkin. Experimental results showed that kinetics of MB adsorption by our ACFB adsorbent followed pseudo-second order model. Maximum adsorption capacity obtained was 330 mg/g, which indicated that fir bark is an excellent raw material for low-cost production of activated carbon suitable for cationic dye removal.
Data from: Removal of Cr6+ ions from water by electricosorption on modified activated carbon fibre felt
Electrosorption is a novel desalination technique that has many advantages in the treatment of sewage. However, commercially available activated carbon electrodes for electrosorption commonly have low microporosity, poor molding performance, and low adsorption and regeneration efficiency. Here we evaluated a novel adsorbent material, activated carbon fiber felt (ACFF), for electrosorption of chromium ions (Cr6+) in sewage treatment. The ACFF was modified with 20% nitric acid and its modified structure was characterized. The modified ACFF was used as an adsorbing electrode to investigate its desalination effect by electrosorption. Results showed that compared with those of unmodified ACFF, the modified ACFF had more carbonyl and carboxyl groups and the specific surface area, average pore size and micropore volume of the modified ACFF also improved by 32.2%, 2.5%, and 23.1%, respectively. The kinetics of Cr6+ adsorption conformed to the pseudo-second order kinetic equation, and the adsorption isotherm conformed to the Langmuir model. In addition, the regeneration rate of the modified ACFF electrode was more than 94%. In conclusion, the modified ACFF exhibits excellent electrosorption and regeneration performance for Cr6+ removal from water and thus is of great value for promotion in sewage treatment.

Dataset for the project "The role of expansive and invasive plant species in shaping the activity of microbial communities and carbon sequestration in the soil of post-mining spoil heaps."
<p>Description of the project: Research on carbon sequestration in all types of ecosystems, including human-transformed oligotrophic ecosystems, has become more important today from a climate change perspective, as it can help mitigate its effects. Increasing the potential for C sequestration on brownfield sites can be achieved by improving biological processes and developing soil organic matter reservoirs. This may be particularly relevant for the functioning of oligotrophic ecosystems such as waste coal mine spoil heaps. In studies conducted to date on soil carbon dynamics, it has been found that carbon storage capacity is related to vegetation type, among other factors. This is mainly due to the fact that different plant species affect the physical and chemical properties of the soil, the chemical composition of the litter, detritus supply and rooting depth differently. Furthermore, plant species have been shown to influence the composition and biomass of soil microbial communities, and these microorganisms are responsible for the decomposition of organic compounds in the soil. There is little knowledge of soil microbial communities and their activities in the different plant communities of post-mining spoil heaps, especially with regard to the effects of specific microbial communities on soil carbon sequestration. The aim of the project was to compare the influence of a native expansive grass species (<em>Calamagrostis epigejos</em> (L.) ROTH) and an alien invasive species (<em>Solidago gigantea</em> AITION) on the activity and structure of soil microorganisms and carbon sequestration on post-mining spoil heaps spontaneously colonised by vegetation and subjected to reclamation. The study was carried out on a model post-mining heap, part of which has been reclaimed with overburdened soil, while the remaining part has not undergone any reclamation and is subject to spontaneous succession processes. An analysis of total organic carbon (TOC) in soil substrate samples was carried out to determine the effect of the plant species studied on carbon sequestration. TOC consists of organic compounds mainly derived from root exudates, microbial biomass and decomposition of plant litter and SOM by microorganisms. Therefore, the structure of soil microbial assemblages was also investigated by means of phospholipid fatty acid profiles and the activity of these microorganisms, by means of soil enzyme analysis and functional diversity of microorganisms using BIOLOG<sup>®</sup> Ecoplates. In addition, the in situ level of CO<sub>2</sub> release from the soil was also determined.</p>
