This Small Business Innovation Research Phase I project addresses the development of electrochemically regenerable ion-exchange resins. Electrochemical regeneration offers significant advantages in reduction of the volume of secondary waste generated during target ion recovery. The technology targets the recovery of bichromate from industrial process waste and hazardous waste sites. The proposed technology will dramatically decrease disposal costs for chromium waste in the targeted industries. In this phase, synthesis and characterization of the proposed ion-exchange materials will be carried out utilizing established techniques. Preliminary evaluation of the proposed materials in the removal of bichromate will be performed for a variety of waste simulate compositions to establish selectivity, efficiency, and stability. Electrochemical activation and regeneration of the proposed material will also be demonstrated prior to Phase II scale up and optimization.The proposed ion-exchange resin will reduce raw materials and disposal costs for a number of industries currently using bichromate. These industries include leather tanning, pigment production, wood preservatives production and metal treatment. The proposed technology is aimed toward waste reduction, resource recovery and toxic waste cleanup with a potential market of $60 million.

这个小企业创新研究的第一阶段项目致力于电化学可再生离子交换树脂的开发。电化学再生在减少目标离子回收过程中产生的二次废物体积方面具有显著的优势。该技术的目标是从工业过程废物和危险废物场地中回收重铬酸盐。所提出的技术将大大降低目标工业中铬废物的处理成本。在这一阶段，离子交换材料的合成和表征将利用现有的技术进行。将对所提出的材料在去除重铬酸盐方面进行初步评估，以确定各种废物模拟组合物的选择性、效率和稳定性。在第二阶段扩大规模和优化之前，还将演示拟议材料的电化学活化和再生。提出的离子交换树脂将减少原材料和处理成本的一些行业目前使用重铬酸盐。这些行业包括皮革制革、色素生产、木材防腐剂生产和金属处理。拟议的技术旨在减少废物、回收资源和清理有毒废物，潜在市场为6 000万美元。
