“…The physicochemical properties of the adsorbents are shown in Table 1. Most of the values are in agreement to those reported in literature; specific surface area (SAA) of talc and kaolinite (Ouchiar et al 2015), cation exchange capacity (CEC) of vermiculite (Sutcu 2015), pH of vermiculite (Rashad 2016a), pH of perlite (Rashad 2016b), CEC and SAA of perlite (Tekin et al 2010), CEC of FA (Visa 2016), SAA of FA and CEC of talc (Dellisanti et al 2009).…”

This paper describes study of ciprofloxacin and isoniazid removal from aqueous solutions using coal fly ash (FA), kaolinite, perlite, talc and vermiculite. The adsorptive features of the adsorbents were evaluated for ciprofloxacin and isoniazid with regards to the effects of contact time, pH, the solid/liquid ratio and antibiotic concentration. All adsorbents were sterilised by dry heat before use to avoid the proliferation of antimicrobial resistance by the bacteria present on the adsorbents during experiments. The regression correlation coefficients indicate that the Langmuir model gives the best fit for the sorption of both antibiotics onto FA and talc, ciprofloxacin onto kaolinite, and isoniazid onto perlite and vermiculite with R2 values ranging from 0.908 – 0.999. The Freundlich isotherm best describes the sorption of ciprofloxacin onto vermiculite and isoniazid onto kaolinite with R2 values of 0.999 for both. The Tempkin model best describes the sorption of ciprofloxacin onto perlite with an R2 = 0.997. The values of the Freundlich exponent, 1/n, range from 0.221 – 0.998, indicating a favourable adsorption of ciprofloxacin and isoniazid onto the adsorbents. The heat of sorption, B, calculated from the Temkin plots has values ranging from 0.018 – 10.460 J/mol, indicating a physical adsorption process (physisorption). Adsorption equilibrium was achieved after 30 min for both antibiotics and the kinetic data obtained conforms best to the pseudo-second order equation with R2 values ranging from 0.998 – 0.999. The removal of ciprofloxacin and isoniazid by all adsorbents except FA was strongly influenced by the pH suggesting that electrostatic interactions play a major role in the adsorption processes.

“…Much attention is thus devoted to PLA nucleating agents, organic [21][22][23], such as sodium benzoate, or inorganic, such as calcium carbonate, talc, boron nitride [24,25] to better tune crystallization rate and final crystallinity content. Nano-fillers, such as cellulose nano-whiskers [26], carbon nano-tubes [27] or graphene oxide [28] were also reported to act as nucleating agents for PLA, although composition and geometrical characteristics of the nano-fillers were reported to have a strong effect on overall crystallization rate.…”

The aim of this chapter is to introduce to the use and possible applications of polylactide-based composites. Polylactides are biodegradable aliphatic polyesters, which are widely used in medical and ecological-friendly fields. First of all, a deep description of main characteristics of polylactides is shown. This chapter summarizes many concepts, which comprehend a general view of polylactide biopolymers such as synthesis and structures, physical-chemical and mechanical characterization and possible applications of final products. Then, an overview of composites based on polylactides and their benefits compared with bare polylactides are described.
