This study reports the successful transformation of mulberry wood waste
into natural textile dye and adsorbent for Pb2+ ions from an aqueous solution. Fabrics of different chemical compositions were dyed using mulberry
wood extract, whereas wool possessed the best appearance and color fastness to washing. Among differently dyed wool fabrics, those dyed with 15%
extract for 5 h has the highest color strength (K/S = 11.24) and antioxidant
activity (83.5%), and the best color and antioxidant activity fastness to
washing, making it appropriate for protecting the skin from diverse damages
by decelerating the effect of free radical. Moreover, it could be suggested
that the binding mechanism proceeds via strong hydrogen bonds between
wool surface carboxylate groups and characteristic phenolics found in the
extract (dominantly taxifolin, oxyresveratrol, ellagic acid, and tannins). The
mulberry wood solid parts separated after the extraction were further evaluated as adsorbents for Pb2+ ions. The highest lead removal was achieved at
a solution pH of 5.5, while the equilibrium removal was reached after 4 h of
contact time. At 20 mg/l initial lead concentration, the mulberry wood waste
removal efficiency was 98.8%. The results of this study represent a step
forward to a healthier, cleaner, and more sustainable society, 摘要
本研究报告了将桑木废料成功转化为天然纺织染料和水溶液中Pb2+ 离子
的吸附剂. 不同化学成分的织物用桑木提取物染色, 而羊毛的外观和耐洗色
牢度最好. 在不同染色的羊毛织物中, 用15%提取物染色5小时的羊毛织物
具有最高的颜色强度 (K/S = 11.24) 和抗氧化活性 (83.5%), 并且具有最佳的
颜色和抗氧化活性耐洗牢度, 因此适合通过减缓自由基的作用来保护皮肤
免受各种损伤. 此外, 可以认为, 结合机制是通过羊毛表面羧基和提取物中
的特征酚类 (主要是紫杉醇, 白藜芦醇, 鞣花酸和单宁) 之间的强氢键进行
的. 提取后分离的桑木固体部分被进一步评估为Pb2+ 离子的吸附剂. 在溶
液pH值为5.5时, 铅的去除率最高, 而接触时间为4小时后, 铅的去除率达到
平衡. 在20mg/l的初始铅浓度下, 桑木废弃物的去除率为98.8%. 这项研究的
结果代表着朝着一个更健康, 更清洁, 更可持续的社会迈进了一步.",
