The presented work shows the synthesis and characterization of Zn/Ti layered double hydroxide (LDH) intercalated with carbonate and dodecyl sulfate ions following its application as a functional filler in LDPE in order to improve the thermal properties and resistance degradation in UV-Vis radiation. X-ray diffractogram patterns of Zn/Ti LDH-CO3 and Zn/Ti LDH-DDS present basal spacing value in the order of 6.81 Å and 38.09 Å, respectively, indicating success in layered compound synthesis. LDPE nanocomposite containing hydrophobic and hydrophilic LDH presented a very well dispersed nanocomposite, as demonstrated in XRD and DSC results. The addition of only 1 % of LDH as filler into LDPE causes an increase of 5.43 oC in the thermal property. Zn/Ti LDH-DDS absorbs more light compared to the Zn/Ti LDH-CO3 due to the enhanced interlayer distance in the presence of DDS in the basal space of LDH, which further the intercalation process of polymer chains within the interlayer regions of LDH.

In this study, zinc layered hydroxide salts (Zn-LHS) intercalated with dodecyl sulfate (DDS) anion in nanocone morphology (LHS-NC) and conventional stone-like co-precipitation LHS phases (LHS-CO) were investigated as adsorbent of Orange G (OG) and Sunset Yellow (SY) dye. LHS-NC was prepared by urea hydrolysis method, while LHS-DDS was prepared by coprecipitation method. XRDP, FTIR, and SEM were used to characterize their structure and showed the formation of layered compounds with very well layered stacking with nanocone and conventional layer stone morphology. After OG and SY adsorption, the results (XRDP, FTIR, UV-Vis, Zetametry) showed that the Freundlich adsorption isotherms had been well fitted, and both OG and SY dyes were intercalated in interlayer space of LHS, where LHS-CO and LHS-NC present high uptake capability of SY dye remotion equal a 227.79 and 442.48 (mg g À 1 ) while OG adsorption capability were 2.52 and 6.39 (mg g À 1 ), respectively. For the kinetics study, the best fit was obtained by the pseudo-second-order model, whereas the results of intraparticle diffusion show a one-step adsorption process. Hence, this study demonstrated Zn-LHS in nanocone morphology, and conventional stone-like co-precipitation phase makes them potentially attractive adsorbents in water purification.
