Abstract

In this research, zero-valent iron (ZVI) was synthesized from kepok banana peels extracts as reducing agent. The fourier transform infrared spectrum showed a clear peak at a wavenumber of 600 cm-1 that could be assigned to Fe-O bond. XRD measurement results prove that ZVI has been successfully formed. The resulting ZVI particles are spherical granules with heterogeneous sizes and close together or agglomerating. Based on the results, it was found that the optimum ratio between FeSO4 and polyphenols for ZVI preparation is 4 : 1. Based on the particle size distribution analysis, it was shown that the optimum feeding temperature and time for ZVI synthesis were 25 oC and 30 minutes, respectively.

Abstract

This study focused on characterizing synthesized silver nanoparticles (AgNPs) and evaluating their efficacy as colorimetric detectors for heavy metal ions. The synthesis employed a bottom-up approach, using AgNO3 as a precursor, reduced by secondary metabolites in basil leaf extract, enhanced with Polyacrylic acid (PAA). Basil leaves were chosen for their rich content of secondary metabolites like phytosterols, alkaloids, phenolic compounds, tannins, lignin, starch, saponins, flavonoids, terpenoids, and anthraquinones, crucial in reducing silver ions. Incorporating basil leaf extract as a bioreactor and adding PAA to increase stability and selectivity towards metal ions are innovative aspects of this research. The optimal AgNP composition was attained with a 0.7 mL basil leaf extract to 10 mL AgNO3 ratio plus 2% PAA. The AgNP formation was indicated by a color change from yellow to brownish, with a Surface Plasmon Resonance (SPR) peak at 418 nm. Characterization via Fourier Transform Infrared Spectroscopy (FTIR) revealed hydroxyl (-OH) and carbonyl (C=O) functional groups aiding in silver ion reduction. Particle Size Analysis (PSA) showed AgNPs of 72.3 nm size, with a polydispersity index of 0.504. Colorimetric detection tests were conducted on Cu(II), Pb(II), Cd(II), Zn(II), and Mn(II) ions. AgNPs exhibited high reactivity towards Cu2+, changing color from brownish to clear white within a minute upon Cu2+ addition, unlike Cd2+, Mn2+, Zn2+, and Pb2+, which showed negligible changes. This indicates a heightened sensitivity of AgNPs to Cu2+ ions. Such a colorimetric sensor could be instrumental in detecting heavy metals in drinking water, showcasing the potential application of AgNPs in environmental monitoring.

Abstract

This study aims to find out the misconceptions that occur in buffer solution materials using two-tier diagnostic tests instrument. The instrument was developed based on the buffer solution material competency indicators into 10 questions and was declared valid for use. The research was conducted on level I and III college students and students totaling 159. The results showed that there was a misconception on the concept of buffer solution properties of 24.6%, the concept of buffer solution composition was 24.1%, the working principle of buffer solution was 29.3 %, and the concept of pH solution is 25.4%. he cause of the misconception is because the initial concept of the respondent is weak, the teacher's explanation often simplifies the concept, the habit of the respondent to memorize, understanding the language and weak mathematical concepts, and learning models that have not provided the opportunity for respondents to understand the components and principles of working buffer solutions microscopically. Knowledge of misconceptions is needed as an evaluation of teachers and lecturers to be more motivated to implement learning models that are able to overcome misconceptions to prevent wider misconceptions in learning chemistry that make chemistry difficult.
