Dataset for adsorptive removal of tetracycline (TC) from aqueous solution via natural light weight expanded clay aggregate (LECA) and LECA coated with manganese oxide nanoparticles in the presence of H2O2

Abstract

In this data article, natural (NL) and manganese oxide-modified LECA (MML) adsorbents were applied for adsorptive removal of Tetracycline (TC) from aqueous solution. The used adsorbents was characterized using fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray fluorescence spectroscopy (XRF). The chemical analysis of XRF data revealed increased chemical composition of Mn as MnO to 8.96 wt%. The SEM patterns were illustrated the extent of surface and enhanced porosity in MML with Mn. In optimum operational conditions, maximum removal percentage of TC was achieved at 51.5 and 99.4% using NL and MML, respectively. The maximum adsorption capacities obtained from Langmuir modeling were 6.89 and 9.24 for NL and MML, respectively. The modeling of the adsorption kinetics revealed that TC adsorption by both NL and MML adsorbents was best-fitted with a pseudo-first-order model ( R 2 = 0.978). The isotherm studies of TC adsorption by MML showed that the Freundlich isotherm was the most appropriate model, with a higher coefficient of determination. The obtained data was illustrated that high competitive capacity of chloride and hardness ions compared with other ions against TC adsorption.

Photocatalytic Platforms for Removal of Ammonia from Gaseous and Aqueous Matrixes: Status and Challenges

“…In addition to polymers, inorganic minerals such as light-expanded clay aggregates (LECA) can serve as effective support materials owing to their adsorption capacity and stable structure. − In this regard, a TiO 2 /LECA composite achieved reasonably enhanced photocatalytic performance toward NH 3 (aq) at a pH of 11 (QY of 2.81 × 10 –05 molecules photon –1 and SY of 2.25 × 10 –10 molecules photon –1 mg –1 ) (Table ). A four-step physicochemical procedure was applied to regenerate the spent TiO 2 /LECA material: (i) washing with distilled water to remove weakly adsorbed pollutant molecules from the catalyst surface, (ii) aeration to remove more strongly adsorbed pollutant molecules from the catalyst pores, (iii) ion exchange using 3 g L –1 of NaCl (3 h) to remove adsorbed NH 4 + ions, and (iv) heat treatment (250 °C for 0.5 h) to remove the remaining pollutant molecules from the catalyst surface …”

The Adsorption Characteristics of Heavy Metals in Acid Mine Drainage from Abandoned Tin Mines on Lightweight Expanded Clay Aggregate (LECA)

“…Materials for Electronics and Sensors [17], metronidazole [18], E. coli [19], COD [3], copper [15], lead and cadmium in paint industry's effluents [20], oil spill from an aquatic environment [21], also Pb(II), Cd(II), Ni(II) and Ba(II) in drinking water [22]. Many studies of metal remediation using adsorption methods have been carried out, but adsorption of heavy metals in acid mine drainage from tin mines is still rare.…”
