“…Pb was slightly complicated, it seemed the adsorption capacity of Pb was sensitive to impregnation ratio, but the minimal value also appeared at the ratio of 1.5. This may due to the fact that, when the impregnation ratio was relatively low, the impregnation of raw materials by phosphoric acid is not sufficient, the specific surface area and pore volume was small, the adsorption capacity of HMs was week, the specific surface area and the adsorption capacity of HMs increased with the increase of impregnation ratio in the first phase323435. But superfluous activator could prevent the shrinkage of raw materials, which will cause the reduction of the special area and the diminution of the adsorption capacity.…”

This present paper was focused on the manufacture of activated carbon (AC) and its application in the electrokinetic remediation (EKR) technology on removal of the heavy metals (HMs) from the municipal solid waste incineration fly ash. AC was produced from Neosinocalamus affinis (NF) by chemical activation with H3PO4 in N2 atmosphere, the effects of activation temperatures, soaking time and impregnation ratios on the adsorption capacity of AC on HMs were examined through equilibrium adsorption experiments. The AC produced under the condition of 450 °C of activation temperature, 10 h of soaking time and 1.5 of impregnation ration was applied in the EKR experiment. The addition of AC in the S3-region of the electrolyzer could effectively improve the removal efficiencies of HMs. The technical parameters of voltage gradient, processing time and proportion were further optimized in the coupled experiments, the maximum removal of Cu, Zn, Cd, and Pb was 84.93%, 69.61%, 79.57%, and 78.55% respectively obtained under the optimal operating conditions of 2 V/cm of voltage gradient, 8 d of processing time and 20% of proportion.

“…For qualitative investigation of functional groups, the FTIR spectra were recorded in the range of 4,000–400 cm −1 as plotted in Figure 2. The peaks appearing at 3,380 and 576 cm −1 can be attributed to the moisture content or –OH group for all samples (Hata et al, 2016; Mahmoud et al, 2017; Shah et al, 2015) and the stretching vibration of Fe‐O, respectively (Chowdhuri et al, 2016; Li et al, 2017). For MAC, the bands at 1,695 and 1,520 cm −1 are ascribed to C=O and the vibration mode of oxygen atoms, respectively (Li, Du, et al, 2013; Lin et al, 2014; Petit & Bandosz, 2012).…”

Bi‐metallic and tri‐metallic metal–organic frameworks (MOFs) supported on the magnetic activated carbon (MAC) were synthesized for the reduction of methylene blue (MB) concentration in the aqueous solutions. The adsorbent nanocomposites were characterized by applying the general tests including XRD, FTIR, FESEM, TEM, BET, and VSM. The XRD achievements demonstrated that crystalline structure of MOFs was derived on the MAC by the presented method. The core–shell morphology with nano‐scale size of the magnetic carbonaceous MOFs was detected in TEM and FESEM micro‐images. The acceptable magnetic strength of the prepared adsorbents was proved by using the VSM analysis. The important operating conditions including pH and temperature were also evaluated, while the other parameters were kept constant. The pseudo‐second‐order kinetic model was matched with the experimental data to show the kinetic behavior of the multi‐component MOFs. The isotherm studies showed that the good agreement between the experimental data with both Langmuir model and the maximum capacities was calculated to be about 66.51 and 71.43 mg/g for the bi‐metallic and tri‐metallic nanocomposites, respectively. Regeneration experiments indicated that the fabricated adsorbents have an excellent reusing adsorption capacity which can be a proper selection for the industrial applications. Practitioner points Bi‐metallic and tri‐metallic MOFs supported on the magnetic activated carbon were synthesized by the facile preparation method. Adsorption of methylene blue by using MOFs were successfully done. Nanocomposites were evaluated by XRD, FTIR, BET, FESEM, TEM, and VSM techniques. Maximum of adsorption capacity was observed for tri‐metallic MOF as 71.43 mg/g.

Nitrogen from secondary effluents has endangered the aquatic environment and human health. A new experimental setup combining a corncob carbon source and bamboo charcoal filter (BCF) was used to effectively purify artificial sewage treatment plant tail water that had high nitrate and nitrogen content, and a low carbon to nitrogen (C/N) ratio. The nitrogen concentration in the reactor's effluent was below the limit of 15 mg/L when the influent COD concentration was 20 mg/L-60 mg/L, the influent NO 3-N concentration was 15 mg/L-30 mg/L, and the hydraulic retention time (HRT) was 1 h-4 h. The reactor's maximum volumetric load of total nitrogen was 0.585 kg/(m 3 •d). The COD and NO 3-N balances of the reactor indicated that 4.77 g corncob was required to remove 1 g NO 3-N and 2 g corncob was required to release 1g COD.
