The adsorption experimental results show that W₁₈O₄₉ with oxygen vacancies not only has faster adsorption rates for MB but also has larger adsorption capacities than WO₃. Besides, the maximum adsorption capacity of urchin-like W₁₈O₄₉ (375.94 mg/g) is about 2.76 times of WO₃ (136.25 mg/g). However, photocatalytic results revealed that WO₃ has better photocatalytic degradation ability than W₁₈O₄₉. Generally, the adsorption efficiency of urchin-like W₁₈O₄₉ (70.01%) is about 3.94 times of WO₃ (17.78%), while the photodegradation efficiency of WO₃ (62.45%) is 2.38 times of urchin-like W₁₈O₄₉ (26.20%). Therefore, urchin-like W₁₈O₄₉ has the best total removal efficiency, which can remove 96.21% of MB (50 ml, 90 mg/L) within 120 min. These studies emphasize the comprehensive effects of WO₃ and W₁₈O₄₉ on dye removal from two aspects of adsorption and photocatalysis and provide strategies for the preparation of efficient dye removal materials.

吸附实验结果表明，具有氧空位的W ₁₈ O ₄₉不仅对MB的吸附速率更快，而且吸附能力大于WO ₃。此外，类海胆W ₁₈ O ₄₉（375.94 mg / g）的最大吸附能力约为WO ₃（136.25 mg / g）的2.76倍。然而，光催化结果表明WO ₃具有比W ₁₈ O ₄₉更好的光催化降解能力。通常，顽童状的W ₁₈ O ₄₉（70.01％）的吸附效率约为WO _3的3.94倍（17.78％），而WO ₃（62.45％）的光降解效率是野孩子状W ₁₈ O ₄₉（26.20％）的2.38倍。因此，类似顽童的W ₁₈ O ₄₉具有最佳的总去除效率，可以在120分钟内去除96.21％的MB（50 ml，90 mg / L）。这些研究从吸附和光催化两个方面着重强调了WO ₃和W ₁₈ O ₄₉对染料去除的综合作用，并为制备有效的染料去除材料提供了策略。
