Each year, nearly 30 million tons of pineapple fruit are harvested for food and drinking industries, along with the release of a huge amount of pineapple wastes. Without the proper treatment, pineapple wastes can cause adverse impacts on the environment, calling for new technologies to convert them into valuable products. Here, we review the production and application of adsorbents derived from pineapple wastes. The thermal processing or chemical modification improved the surface chemistry and porosity of these adsorbents. The specific surface areas of the pineapple wastes-based adsorbents were in range from 4.2 to at 522.9 m·g. Almost adsorption systems followed the pseudo second order kinetic model, and Langmuir isotherm model. The adsorption mechanism was found with the major role of electrostatic attraction, complexation, chelation, and ion exchange. The pineapple wastes based adsorbents could be easily regenerated. We suggest the potential of the pineapple wastes towards circular economy.
每年，有近 3000 万吨菠萝果实被用于食品和饮料行业，同时也产生了大量的菠萝废料。如果没有适当的处理，菠萝废料可能会对环境造成不利影响，因此需要新技术将其转化为有价值的产品。在这里，我们综述了由菠萝废料衍生的吸附剂的生产和应用。热加工或化学改性改善了这些吸附剂的表面化学和孔隙率。菠萝废料基吸附剂的比表面积在 4.2 到 522.9 m·g 之间。几乎所有的吸附体系都遵循准二级动力学模型和朗缪尔等温线模型。吸附机制主要是静电吸引、络合、螯合和离子交换。菠萝废料基吸附剂可以很容易地再生。我们提出了菠萝废料在循环经济中的潜力。
