一般描述

无水硫化钠98％是一种化合物，呈黄色至白色晶体固体，具有强烈的硫化氢气味。它是一种高度反应性的无机硫属化合物，具有还原剂的作用，因此在许多化学过程中是必不可少的试剂。无水硫化钠可在水中分解并形成碱性溶液。我们的无水硫化钠经过严格干燥工艺，适用于对水分或潮气敏感的应用。

应用

无水硫化钠98%常用于制造纸制品的纸浆和造纸工业中。它也作为漂白剂，用于从木浆中去除木质素。在纺织工业中，它被用作棉毛纤维的染色剂。在皮革工业中，无水硫化钠98％用于从动物皮革中去除毛发和羽毛，并作为一种鞣制剂。此外，它还用于硫染料、杀虫剂和药品的生产。它还具有还原性，因此可用于有机化合物的合成，例如硫代酯和硫代酮。无水硫化钠98％也广泛用于矿物浮选工艺，有助于将有价矿物从矿石中分离出来。

特点和优势

A highly selective circular dichroism sensor based on cysteamine-capped cadmium sulfide quantum dots (Cys-CdS QDs) was successfully developed for the determination of Cu2+. Basically, the Cys-CdS QDs are not active in circular dichroism spectroscopy. However, the circular dichroism probe (DPA@Cys-CdS
