“…As a result, the R 2 value of pseudo-second-order kinetic model is about 0.99 and the calculated q e,cal is very close to the experimental q e,exp , demonstrating that the kinetics data fits well with the pseudo-secondorder kinetic model. Similar phenomenon has been reported in the adsorption of TCP on zeolite and cob carbon [44,45].…”

a b s t r a c tWe present here a novel, low cost and environmental-friendly synthetic strategy for fabricating flowerlike magnetic mesoporous carbon (MMC) microspheres by using silica coated ), as well as good chemical inertness and mechanical stability. The MMC spheres were used to adsorb 2,4,6-trichlorophenol (TCP) from simulated water samples. Experiment results suggest that the adsorption was favorable at acidic pH and increased with the rise of initial TCP concentration and temperature. Kinetic parameters were proved to follow the pseudo-second-order kinetics model and the equilibrium data was more favorable for Freundlich isotherm. The equilibrium absorption capacity was 210 mg g À1 at initial TCP concentration of 20 mg L À1and increased to 587 mg g À1 when the initial TCP concentration was up to 100 mg L À1, which was much higher than those of other carbon-based adsorbents reported in literature. To the best of our knowledge, this is the first report on the synthesis of flowerlike MMC material by using LDH as template and its application as adsorbent to remove TCP.

“…Petroleum residues, natural coal and woods were for a long time, the main AC precursors. However, in recent years, easily available natural materials such as pumpkin seed hull [14], coconut bunch waste [15], broad bean peels [16], grass waste [17], pineapple stem waste [18], spent tea leaves [19], etc., and synthetic materials/wastes have been processed at low cost and have been tested as raw materials for manufacturing AC or biosorbents [7,[20][21][22][23][24][25], so-called because of their renewable character, a factor which will contribute to mitigating the problem of waste disposal. Moreover, both the regeneration of the adsorbent [26] and the recovery of the adsorbate at competitive rates [27] have been reported in the literature.…”

“…This is because the pH of the solution affects the degree of ionization and the speciation of TC-HCL which subsequently leads to a change in adsorption kinetics and equilibrium characteristics (Sathishkumar et al 2009). Chang and colleagues have already reported various forms of TC exist in different pH (Chang et al 2012).…”

Herein, we explain an effective method for the synthesis of halloysite/CoFe 2 O 4 magnetic composites (magnetic halloysite nanotubes or MHNTs) and their use as as adsorbents to effectively remove tetracycline hydrochloride (TC-HCl) from aqueous solutions. The synthesized composites were characterized by the following methods: Fourier transform infrared, X-ray diffraction, transmission electron microscopy, vibrating sample magnetometry and atomic absorption spectrometry. Our study results indicated that MHNTs have strong magnetic (Ms = 34.02 emu/g) and low leakage properties. The adsorption capacities of MHNTs were investigated by performing a series of experiments with different pH, temperatures, initial concentrations and reaction time. The Langmuir isotherm model fitted to equilibrium data better than the Freundlich model. The kinetic properties of the composites were well-described by applying the pseudo-second-order equation. Even after carrying out two repeated experimental cycles, the reusability of the synthesized composites did not obviously degenerate.
