中文摘要: 光伏电站的大力开发同时伴随着大量废旧太阳能电池板的产生,亟需开发环保高效的技术解决废旧太阳能电池板带来的问题。探讨了废旧太阳能电池板预处理技术及其带来的损失情况,再利用正交试验优化了影响废旧太阳能电池板中银高效提取的因素及其影响程度。结果表明,人工拆解和热处理都会造成废旧太阳能电池板质量的损失,且拆解程度越深,损失越大。废旧太阳能电池板中银提取的最佳条件为:甲磺酸浓度40%、过氧化氢浓度20%、反应时间2.5 h、反应温度70 ℃,银的浸出率可达97.85%,相对标准偏差为2.16%。各因素对银浸出率的影响程度大小为:甲磺酸浓度>反应时间>反应温度>过氧化氢浓度。
Abstract:The vigorous development of photovoltaic power stations is accompanied by generation of a large number of waste solar panels. It is urgent to develop environmentally efficient technologies to solve the problems brought by waste solar panels. Pretreatment technology of waste solar panels and loss caused by it were discussed, and then the factors affecting efficient extraction of silver from waste solar panels and their impact were optimized by orthogonal experiment. The results indicate that both manual disassembly and heat treatment will cause weight loss of waste solar panels, and the more thorough the disassembly, the greater the loss. Silver leaching rate is 97.85 % with RSD of 2.16% under the optimum conditions for silver extraction from waste solar panels including mesylate concentration of 40%, hydrogen peroxide concentration of 20%, reaction time of 2.5 h, and reaction temperature of 70 ℃. The influence sequence of each factor on silver leaching rate is mesylate concentration > reaction time > reaction temperature > hydrogen peroxide concentration.
