摘要： 研究型实验教学是当前高校实验教学的研究热点。硝酸银是一种价格比较昂贵的试剂，从含银废液中回收硝酸银，不仅能解决环境污染问题，也能节约实验成本。该实验所需仪器设备简单，涉及的操作及过程中出现的问题等，学生也能够利用所学知识和技能有效解决。本文以含银废液为原料回收硝酸银为实验项目，让学生自己设计实验方案，并通过方案的实施，体验研究型实验教学的过程，达到培养学生科学研究意识的目的。

Abstract: Research-oriented experimental teaching has emerged as a prominent focus in higher education’s pedagogical studies. Silver nitrate, a notably costly reagent, poses a dual opportunity when recovered from silver-containing waste: it mitigates environmental pollution and reduces experimental costs. The experiment requires simple equipment, enabling students to apply their learned knowledge and skills effectively in resolving operational and procedural challenges. This study utilizes the recovery of silver nitrate from silver-containing waste liquid as the experimental project, where students independently devise their experimental strategies. Through the implementation of the scheme, they engage in a research-based learning process, thereby fostering their scientific research acumen.
