在本发明描述对于染料去除有用的半导体氧化物纳米管基复合材料颗粒和其方法，它涉及包括水溶液中暗条件下操作的离子交换机制、用于处理产品的方法，该产品由沉积(或锚定或附着)到飘尘颗粒和金属氧化物(磁性和非磁性)纳米颗粒上的半导体氧化物的纳米管组成。生成的微纳米和纳米-纳米完整的复合材料颗粒发现，在从水溶液和工业废水中去除有机合成染料的潜在的应用，经过表面吸附方法，包括离子交换和静电吸引机制，在暗条件中操作。复合材料颗粒可以循环用于染料吸附的下个循环，通过分解在其表面上先前吸附的染料，经过使用贵金属沉积的光催化剂或者磁性可分离的光催化剂以及暴露于紫外(UV)或日光照射。 Semiconductor-oxide nanotubes-based composite particles are useful for dye-removal. A method involves an ion-exchange mechanism operating under a dark-condition in an aqueous solution, for the processing of products consisting of the nanotubes of semiconductor-oxides deposited on, anchored to or attached to the surface of fly ash particles and metal-oxide (magnetic and non-magnetic) nanoparticles. The resulting micro-nano and nano-nano integrated composite particles can be used in the removal of an organic synthetic-dye from an aqueous solution and industry effluent via a surface-adsorption process, involving ion-exchange and electrostatic-attraction mechanisms. The composite particles can be recycled for the next cycle of dye-ad
