Introduction

Dopan nanopartikel perak dari air limbah radiofotografi yang diembankan pada fotokatalis tio2: material antijamur dan antibakteri masa depan. Mengulas sintesis nanopartikel perak dari limbah radiofotografi untuk fotokatalis TiO2/AgNPs. Membandingkan metode & karakterisasi material antijamur/antibakteri masa depan ini.

Abstract

Air limbah radiofotografi mengandung ion kompleks perak tiosulfat [Ag(S2O3)2]3-. Kation Ag+ dapat direduksi menjadi Ag(s), yang digunakan sebagai dopan untuk diembankan pada fotokatalis TiO2. Penggunaan dopan Ag yang berasal dari air limbah fixing radiofotografi yang disintesis oleh 3 penelitian yang berbeda. Tujuan utama dari review paper ini adalah untuk membandingkan hasil yang diperoleh 3 artikel terindeks Scopus tersebut, baik dari segi konsentrasi Ag(I) yang diperoleh dari air limbah radiofotografi, metode pembuatan fotokatalis TiO2/AgNPs, karakterisasi yang dilakukan pada berbagai instrumen, dan hasil pengujian in vitro pada organisme uji.

Review

The paper presents a timely review addressing the innovative recovery of silver nanoparticles from radiophotography wastewater for use as a dopant in TiO2 photocatalysts, aiming to develop future antifungal and antibacterial materials. The premise of utilizing industrial waste as a valuable resource to synthesize advanced functional materials is highly relevant to contemporary sustainable chemistry and material science. Crucially, the abstract clarifies that this is a *review paper*, focusing on synthesizing and comparing findings from three distinct Scopus-indexed articles. The primary objective is to systematically evaluate these studies across key parameters, including Ag(I) concentration obtained from wastewater, TiO2/AgNPs synthesis methodologies, characterization techniques, and the efficacy of the resulting materials in *in vitro* antimicrobial tests. The strength of this work lies in its clearly defined scope and comparative approach. By analyzing and contrasting three different studies, the review promises to offer valuable insights into the varying efficiencies of silver recovery, the reproducibility of synthesis methods for TiO2/AgNPs, and the consistency of observed antimicrobial properties. This structured comparison across multiple studies, encompassing initial silver recovery, material preparation, detailed characterization, and application testing, is vital for identifying best practices, understanding discrepancies, and highlighting successful strategies within this specific research area. Furthermore, the selection of Scopus-indexed articles adds a layer of academic rigor and reliability to the review's foundation. While the abstract outlines a well-structured comparative review, it is important for the final paper to deliver a critical analysis beyond mere comparison. A minor point is that the title, "Dopan Nanopartikel Perak dari Air Limbah Radiofotografi yang Diembankan pada Fotokatalis TiO2: Material Antijamur dan Antibakteri Masa Depan," might be slightly misleading, as it reads more like an original research paper's title rather than a comprehensive review. A more explicit title indicating its review nature would enhance clarity. The review should also endeavor to synthesize the findings into clear conclusions regarding the most promising approaches, identify existing research gaps, and propose future directions for both silver recovery from wastewater and the development of these advanced antimicrobial materials. This would significantly enhance its contribution to guiding future research and development in this exciting interdisciplinary field.
