Abstract

This research investigates the optimized biosorption of zinc ions using lignocellulosic materials derived from Vitis vinifera, specifically grape stems and vine shoots. The study aims to address heavy metal pollution by utilizing agricultural waste for sustainable and cost-effective zinc ion removal from wastewater. The biosorbents were prepared and characterized, and key parameters such as initial zinc ion concentration, pH, biosorbent dose, and stirring time were optimized using Response Surface Methodology with Box-Behnken Design. The kinetics of adsorption were represented by pseudo-first-order and pseudo-second-order models, while the equilibrium isotherms were characterized using Langmuir and Freundlich models. The research achieved zinc ion removal efficiencies of up to 99.41% for grape stems and 91.93% for vine shoots. The optimal conditions for biosorption were found to be a pH of 7, a biosorbent dose of 2.1 g for grape stems and 2.5 g for vine shoots, and a stirring time of 25 min for grape stems and 18 min for vine shoots. Functional groups and alterations in the surface morphology of the biosorbents were verified through Fourier-transform infrared spectroscopy and scanning electron microscopy combined with energy-dispersive X-ray spectroscopy. Life Cycle Assessment provided insights into the environmental impacts of zinc biosorption.

利用葡萄木质纤维素生物质优化Zn（II）生物吸附：动力学、等温线和生命周期评估综述

本研究研究了从葡萄茎和葡萄芽中提取的木质纤维素材料对锌离子的最佳生物吸附。该研究旨在通过利用农业废弃物对废水中的锌离子进行可持续和经济的去除来解决重金属污染问题。采用Box-Behnken设计响应面法对吸附剂的初始锌离子浓度、pH、剂量、搅拌时间等关键参数进行了优化。吸附动力学用拟一级和拟二级模型表示，平衡等温线用Langmuir和Freundlich模型表征。对葡萄茎和藤梢的锌离子去除率分别达到99.41%和91.93%。结果表明，最佳吸附条件为pH = 7，葡萄茎和藤茎的生物吸附剂用量分别为2.1 g和2.5 g，搅拌时间分别为25 min和18 min。通过傅里叶变换红外光谱和扫描电镜结合能量色散x射线光谱，验证了生物吸附剂的官能团和表面形貌的变化。生命周期评估提供了锌生物吸附对环境影响的见解。

期刊介绍： Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments. Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation. Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
