Ferric ion modified attapulgite (Fe/ATP) was prepared by impregnation and its structure and morphology were characterized. The toxicity characteristic leaching procedure (TCLP) was used to evaluate the effect of Cadmium( Cd) stabilization in soil with the addition of attapulgite (ATP) and Fe/ATP. The stabilization mechanism of Cd was further elucidated by comparing the morphologies and structure of ATP and Fe/ATP before and after Cd adsorption.

Article Synopsis
- - The study focuses on N-hexadecylated poly(p-phenylene terephthamide) (PPTAC16), which is a comb-like polymer made from a PPTA backbone with hexadecyl side chains, synthesized through N-alkylation reactions.
- - Characterization techniques such as differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FT-IR) were used to analyze the molecular structure and thermal behavior of PPTAC16, revealing that the crystallization of the hexadecyl side chains is less organized compared to n-hexadecane.
- - The temperature-dependent IR spectroscopic results indicated significant changes in the characteristics of the methylene groups' vibrations, suggesting that the side chains melt
