Solution plasma process is one of the promising techniques which has been applied for the synthesis of carbonaceous materials. This process offers several advantages, for example, simple experimental system, inexpensiveness, short-time operation, and processing at room temperature and atmospheric pressure. In this study, amine-modified on carbon nanoparticles was conducted by facile synthesis via a solution plasma process using the organic mixture of carbon precursor and Amine-terminated silane (ATS) and utilized for heavy metal ions removal application. The characteristic of the adsorbent could be adjusted conveniently by the concentration of ATS. The 3% v/v ATS modified-carbon was effectively promoted in the metal ions removal application. It was observed that the adsorption capacity was ranked in order of 61.79, 57.57, 45.84, and 40.86 mg・g^-1 for Cu²⁺, Pb²⁺, Zn²⁺, and Cd²⁺, respectively. Further investigation revealed that the pseudo-second-order kinetic and the Langmuir adsorption isotherm were provided an accurate description of the equilibrium time and maximum metal ions adsorption on the adsorbent, respectively. Moreover, the heavy metal ions removal efficiency of prepared sample was found to be better than that of amine-modified on various types of conventional adsorbents.
