Biosorption of Species in Multi-Component Systems

生物吸附是一种利用廉价的非生物材料，如微生物生物量、农业副产品和食物垃圾来隔离感兴趣的化学物种的过程。拟议的生物吸附研究计划的最终目标是开发创新技术，以配制基于生物材料的吸附剂，并建立高效率和低成本的吸附过程，用于环境、能源、化学、制药和生物医学应用。具体地说，未来五年的一个目标是开发一种方法学，以在生物吸附材料的形状、大小、吸收能力、稳定性和选择性方面提高质量，并对新型生物吸附颗粒进行配方和表征。生物材料来源将包括亚麻屑、油菜籽干草，以及萨斯喀彻温省和加拿大其他地区农业生产的其他具有成本效益的生物材料。另一个目标是利用新型生物吸附颗粒优化生物吸附过程，以处理含铬和含铅废水等重金属。第三个目标是研制具有增强性能的新型生物吸附剂，分别用于燃料醇和天然气的变压吸附脱水。这项研究将产生三个主要成果：生物吸附技术在重金属废水处理中的应用，燃料酒精和天然气的干燥，为高素质人员提供最先进的培训环境，以及生物技术新发现的机会。将废弃生物材料商业化将增加生物材料生产行业的收入。另一方面，这项研究产生的技术将降低废水处理和燃料酒精和气体加工的成本，这将提高加拿大这些行业的盈利能力，并有利于加拿大的环境。

Biosorption is a process which utilizes inexpensive non-living biomaterials such as microorganism biomass, agricultural by-products, and food wastes to sequester chemical species of interest. The ultimate goal of the proposed biosorption research program is to develop innovative technologies to formulate biomaterial based adsorbents and establish adsorption processes with high efficiency and low costs for environmental, energy, chemical, pharmaceutical, and biomedical applications. Specifically for the next five years, one goal is to develop a methodology to formulate and characterize novel biosorbent pellets with enhanced qualities in terms of biosorbent shape, size, uptake capacity, stability and selectivity. Biomaterial sources will include flax shives, canola hay, and other cost-effective biomaterials generated by agricultural industry in Saskatchewan and other parts of Canada. Another goal is to optimize a biosorption process with the novel biosorbent pellets for heavy metals such as chromium and lead containing wastewater treatment. The third goal is to formulate novel biosorbents with enhanced performance for dehydration of fuel alcohols, and natural gas, respectively, in a pressure swing adsorption process. This research will yield three major results: applications of biosorption technology in treatment of heavy metal containing wastewater, and drying fuel alcohols and natural gas, a state-of-the-art training environment for highly qualified personnel and opportunities for new discoveries in biotechnology. Commercialization of waste biomaterials for the regards would increase the revenue of the biomaterial-producing industries. On the other hand, the technologies generated from this research will reduce the costs of wastewater treatment, and processing of the fuel alcohols and gases, which will enhance the profitability of such Canadian industries and benefit the environment of Canada.
