Direct Blue 86  (Synonyms: Solvent Blue 38)

Direct Blue 86 (Solvent Blue 38) is a myelin-sheath stain, commonly utilized in microscopy to detect demyelination in the central nervous system. Direct Blue 86 also is a dye with various applications including as a commercial dye in the printing of cotton and mucilage glue fabrics^[1].

指南 (以下是我们推荐的方案，本方案仅提供指南，应根据您的具体需要进行修改)。
1. 染料原液制备^[1]
1) 称取适量 Direct Blue-86。
2) 将其溶于100 mL蒸馏水中。
3) 将溶液转移至1000 mL容量瓶中，用蒸馏水定容至刻度，配制浓度为1.0 g/L的原液。
2. 染料工作液制备
1) 取1.0 g/L原液等分。
2) 根据实验要求，用蒸馏水稀释，配制浓度为5至100 mg/L的工作液。
3. 具体吸附步骤 (pH 对吸附的影响)
1) 用 0.1 M HCl 或 0.1 M NaOH 调节初始 pH 值，使其从 1 到 9。
2) 将 6 g/L 橙皮活性炭 (COP) 添加到每份含有 100 mg/L Direct Blue-86 的溶液中。
3) 将悬浮液在室温 (25℃) 下以 200 rpm 的搅拌速度振荡 180 min，这是达到平衡所需的最短接触时间。
4) 测定 Direct Blue-86 的吸附量。
