“…A small peak found at 2223 cm -1 corresponded to the stretching vibration mode of C≡N or C≡N bond. Another small peak was also found at 679 cm -1 -695 cm -1 and was attributed to the symmetric bending vibration mode of the Si-O bond within SiO4 group [20], [26].…”

Waste activated sludge of crumb rubber industry (CRI-WAS) is discarded as waste from wastewater treatment processing. Therefore it is necessary to develop and innovate to convert the material becomes valuables and expected to be an economical adsorbent for metal ion remediation from wastewater. The ability of three types of adsorbents prepared from CRI-WAS for the removal of Zn(II) from aqueous solutions has been investigated. The XRF, BET, SEM-EDX, and FTIR analysis were conducted to characterize the PS (pure sludge), WS (washed sludge) and P600 (pyrolysis at 600 0 C) CRI-WAS types of adsorbents. In the batch system, experimental parameters were investigated, including solution pH, contact time, and adsorbent dose. The data were analyzed by analysis of variance (ANOVA) and a further test Duncan's New Multiple Range Test (DNMRT) at the 5% significance level. The results reveal that all types of adsorbent exhibited good sorption potential at pH 5.0. The P600 has largest adsorption capacity. The maximum adsorption capacity of the adsorbent for Zn(II) was found to be 10.276 mg g-1 , 11.042 mg g-1 and 64.169 mg g-1 for PS, WS and P600 CRI-WAS types of adsorbents respectively. The results showed that the adsorption isotherm data were fitted well by the Langmuir isotherm.

“…The 1400 cm -1 region gives some idea of the relative abundance of CH 2 and CH 3 groupings. The stronger peak at 1045 cm -1 , also associated with Si-O-Si structures, indicates the presence of more silicate functional groups [26], [31]. At 1886 cm -1 and 858 cm -1 exhibit C-H vibrations.…”

“…Such conversion was acceptable at field-scale due to the abolishment of high-pressure vessel and the elimination of alkaline wastewater. But up to date, the effect of heating temperature on the synthesis of magnetic adsorbent from groundwater treatment sludge has yet been reported 10 , 11 , 22 , 23 .…”

In this paper, groundwater treatment sludge (GTS) was recycled as a magnetic adsorbent via a facile calcination process without adding any reductant. The prepared magnetic adsorbents (MAs) were characterized by scanning electron microscopy (SEM), X-ray diffractometer (XRD) and X-ray photoelectron spectroscopy (XPS), vibrating sample magnenometer (VSM) and Mössbauer spectroscopy. The results showed that GTS comprised 33.2% Fe, 1.4% Al and 6.2% Si, and exhibited a weak saturation magnetization of 0.0008 emu/g. Without NaOH, the GTS calcinated at 700 and 500 °C were well magnetized with Ms of 20.1 and 7.1 emu/g, separately, but exhibited a low Ms of 0.43 emu/g at 300 °C. By adding NaOH powder, the Ms of GTS apparently increased to 4.9 emu/g after calcination at 300 °C, and further to 8.5 emu/g at 500 °C. In GTS, about 96.1% Fe was involved in ferrihydrite form. The Ms of calcinated GTS was accompanied with the phase transformation of ferrihydrite to maghemite. Si/Al oxides in GTS coordinated on the surface sites of ferrihydrite and inhibited the conjunction and phase transformation of adjacent ferrihydrite particles, but were effectively desorbed as in the presence of NaOH. Na500, preparing by calcinating GTS at 500 °C with NaOH, showed an optimal total surface sites (Hs) of 0.65 mmol/g. Oxytetracycline (OTC) was used as a target for studying the adsorption characteristics of synthetic magnetic adsorbents and a high adsorption capacity of oxytetracycline of 862.1 mg/g in comparison with the other calcinated GTS, and the adsorption data was consistent with the Langmuir model. By adding 6 g/L Na-500, approximately 100% of oxytetracycline and tetracycline and nearly 40% total organic carbon were removed from real pharmaceutical wastewater. With the method, GTS can be converted in mass production to magnetic adsorbent that exhibits effective application in pharmaceutical wastewater treatment.

“…Oxygen-limited heat treatment makes DWTR be a more reliable adsorbent by increasing specific surface area and the sequestrated carbon [18]. Ultrasonic assisted extraction and synthesis method turns DWTR to be an effective adsorbent for ammonium removal [19]. Another study shows that ultra-sonicated DWTR has an increased enrichment potential of weakly hydrophobic acid [20].…”

a b s t r a c tTo obtain a low-cost adsorbent with a regular shape for the better application in water pollution control practice, drinking water treatment residual (DWTR) was modified by adding different proportions of kaolin clay, and the pellet-type adsorbents were then made under the thermal treatment approach. Response surface methodology (RSM) was applied to optimize the production process and analyze the effects of firing time, firing temperature and DWTR proportion on phosphorus (P) adsorption capacity and mass loss ratio, which was chosen as the parameter of strength of the resultant DWTR-clay pellets. The results showed that an increasing temperature contributes to greater strength but leads to smaller P adsorption capacity, while kaolin clay addition results in an improvement of strength but a decrease of P adsorption capacity. The best P adsorption of 10.2 mg P/g pellet was obtained under the conditions of making the pellet with 40% clay addition while heating at 650°C for 60 min. The strength of DWTR pellet could be increased by thermal treatment with kaolin clay. This study can help the large-scale application of DWTR as a low-cost adsorbent in many kinds of water and environmental engineering practices, such as using DWTR as a substrate in the artificial floating island.
