Meeting the increasing demand of clean water requires the development of novel efficient adsorbent materials for the removal of organic pollutants. In this context the use of natural, renewable sources is of special relevance and sepia melanin, thanks to its ability to bind a variety of organic and inorganic species, has already attracted interest for water purification. Here we describe the synthesis of a material obtained by the combination of sepia melanin and poly(ethylene--maleic anhydride) (P(E--MA)). Compared to sepia melanin, the resulting hybrid displays a high and fast adsorption efficiency towards methylene blue (a common industrial dye) for a wide pH range (from pH 2 to 12) and under high ionic strength conditions. It is easily recovered after use and can be reused up to three times. Given the wide availability of sepia melanin and P(E--MA), the synthesis of our hybrid is simple and affordable, making it suitable for industrial water purification purposes.
满足对清洁水日益增长的需求需要开发新型高效吸附材料以去除有机污染物。在此背景下，使用天然可再生资源具有特殊意义，乌贼墨黑色素因其能够结合多种有机和无机物质的能力，已引起水净化领域的关注。在此，我们描述了一种通过乌贼墨黑色素与聚（乙烯 - 马来酸酐）（P（E - MA））结合获得的材料的合成方法。与乌贼墨黑色素相比，所得的杂化物在较宽的pH范围（从pH 2至12）以及高离子强度条件下，对亚甲基蓝（一种常见的工业染料）表现出高且快速的吸附效率。使用后它易于回收，并且可以重复使用多达三次。鉴于乌贼墨黑色素和P（E - MA）广泛可得，我们杂化物的合成简单且经济实惠，使其适用于工业水净化目的。
