Concern about environmental protection has aroused over the years from a global viewpoint. To date, the ever-increasing importance of biomass as the energy and material resources has lately been accounted by the rising prices for the crude petroleum oil. Rice husk ash, the most appropriate representative of the high ash biomass waste, is currently obtaining sufficient attraction, owning to its wide usefulness and potentiality in environmental conservation. Confirming the assertion, this paper presents a state of the art review of the rice milling industry, its background studies, fundamental properties and industrial applications. Moreover, the key advance on the preparation of novel adsorbents, its major challenges together with the future expectation has been highlighted and discussed. Conclusively, the expanding of rice husk ash in the field of adsorption science represents a viable and powerful tool, leading to the superior improvement of pollution control and environmental preservation.
多年来，人们从全球视角出发开始关注环境保护问题。迄今为止，由于原油价格不断上涨，生物量作为能源和材料资源的重要性日益增加。稻壳灰是高灰生物质废物的最典型代表，由于其在环境保护方面的广泛用途和潜力，目前正受到足够的关注。本文通过对碾米工业及其背景研究、基本性质和工业应用的综述，证实了这一点。此外，还重点讨论了新型吸附剂的制备、主要挑战以及未来展望方面的关键进展。综上所述，稻壳灰在吸附科学领域的广泛应用代表了一种可行且强大的工具，可极大地改善污染控制和环境保护。
