Potensi Limbah Ikan sebagai Adsorben untuk Pengolahan Air Limbah: Tinjauan Literatur

Introduction

Potensi limbah ikan sebagai adsorben untuk pengolahan air limbah: tinjauan literatur. Jelajahi potensi limbah ikan (tulang, sisik) sebagai adsorben alami untuk pengolahan air limbah. Studi ini fokus pada remediasi logam berat seperti Pb, Cd, Cu, dan mineral berlebih.

Abstract

Limbah ikan telah menarik perhatian sebagai bahan baku alternatif dalam pemanfaatannya sebagai bahan remediasi logam berat dalam air yang tercemar. Biochar dari tulang digunakan sebagai adsorben dalam pengolahan pencemaran air karena memiliki luas permukaan dan volume pori yang tinggi. Studi ini membahas potensi pemanfaatan limbah ikan, termasuk tulang dan sisik, sebagai adsorben untuk logam berat seperti Pb(II), Cd(II), dan Cu, juga sebagai adsorben untuk mineral berlebih pada air, seperti besi.

Review

The proposed literature review, "Potensi Limbah Ikan sebagai Adsorben untuk Pengolahan Air Limbah: Tinjauan Literatur," addresses a highly relevant and timely topic in environmental science and sustainable waste management. The abstract clearly outlines the scope, focusing on the utilization of fish waste as an alternative raw material for remediating heavy metals and excess minerals in contaminated water. This aligns well with current global efforts to find cost-effective and eco-friendly solutions for industrial and domestic wastewater treatment, leveraging a readily available and often problematic waste stream. A key strength of this review appears to be its specific focus on various components of fish waste, notably bones and scales, and the mention of biochar derived from bones. This indicates an intention to delve into engineered materials rather than just raw waste, which is crucial for effective adsorption. The targeted pollutants — including Pb(II), Cd(II), and Cu, as well as excess iron — represent a significant range of common water contaminants, suggesting a comprehensive overview of the material's potential applications. Emphasizing characteristics such as high surface area and pore volume points to an analytical approach to the underlying adsorption mechanisms, which is essential for understanding and optimizing their performance. To further enhance the impact of this literature review, it would be beneficial for the authors to critically analyze not only the reported efficiencies but also the various pre-treatment methods, chemical modifications, and regeneration capabilities of these fish waste-derived adsorbents. A comparative discussion with existing commercial adsorbents regarding cost-effectiveness, scalability, and environmental footprint would also add significant value. Ultimately, such a comprehensive review has the potential to serve as a vital resource for researchers and practitioners, accelerating the development and implementation of sustainable and efficient wastewater treatment technologies utilizing a valuable, often overlooked, natural resource.
