利用焙燒暨酸浸法從廢棄LED晶粒中回收鎵金屬資源

為了解決廢棄物的問題，作者吳德懷 這樣論述：

LED是發光二極體(Light Emitting Diode)的簡稱。由於LED燈具有節能、無汞等特性，在照明市場之需求日益增加，LED在許多領域已經取代了傳統光源(白熾燈、螢光燈等)。LED燈之高效率白光照明主要是由LED晶粒中氮化鎵(GaN)半導體所產生。隨著LED市場的擴大，未來將產生大量的LED廢棄物。因此，回收廢棄LED中所含的鎵金屬資源對於資源的可持續利用和環境保護都具有重要意義。本研究以廢棄LED燈珠為對象，利用焙燒與酸浸法從其LED晶粒中回收鎵金屬資源，主要包括三個部分：化學組成分析、氟化鈉焙燒處理與酸溶浸漬等。探討各項實驗因子包括焙燒溫度、焙燒時間、礦鹼比、酸浸漬種類及濃度

、浸漬時間、及浸漬固液比等，對於鎵金屬浸漬率之影響，並與各文獻方法所得到的鎵金屬浸漬效果進行比較。研究結果顯示，LED晶粒中含有鎵5.21 wt.%，氟化鈉焙燒暨酸溶浸漬之最佳條件為焙燒溫度900 ℃、焙燒時間3hr、礦鹼比1:6.95、鹽酸浸漬濃度0.5 M、浸漬溫度25 ℃、浸漬時間10mins、固液比2.86 g/L，鎵金屬浸漬率為98.4%。與各文獻方法相比較，本方法可於相對低溫且常壓下獲得較高之鎵金屬浸漬效果。

The Politics of Trash: How Governments Used Corruption to Clean Cities, 1890-1929

為了解決廢棄物的問題，作者Strach, Patricia,Sullivan, Kathleen S. 這樣論述：

The Politics of Trash explains how municipal trash collection solved odorous urban problems using nongovernmental and often unseemly means. Focusing on the persistent problems of filth and the frustration of generations of reformers unable to clean their cities, Patricia Strach and Kathleen S. Su

llivan tell a story of dirty politics and administrative innovation that made rapidly expanding American cities livable. The solutions that professionals recommended to rid cities of overflowing waste cans, litter-filled privies, and animal carcasses were largely ignored by city governments. When th

e efforts of sanitarians, engineers, and reformers failed, public officials turned to the habits and tools of corruption as well as to gender and racial hierarchies.Corruption often provided the political will for public officials to establish garbage collection programs. Effective waste collection

involves translating municipal imperatives into new habits and arrangements in homes and other private spaces. To change domestic habits, officials relied on gender hierarchy to make the women of the white, middle-class households in charge of sanitation. When public and private trash cans overflowe

d, racial and ethnic prejudices were harnessed to single out scavengers, garbage collectors, and neighborhoods by race. These early informal efforts were slowly incorporated into formal administrative processes that created the public-private sanitation systems that prevail in most American cities t

oday. The Politics of Trash locates these hidden resources of governments to challenge presumptions about the formal mechanisms of governing and recovers the presence of residents at the margins, whose experiences can be as overlooked as garbage collection itself. This consideration of municipal gar

bage collection reveals how political development often relies on undemocratic means with long-term implications for further inequality. Focusing on the resources that cleaned American cities also shows the tenuous connection between political development and modernization.
