Carboxymethyl cellulose (CMC)/titanium dioxide (TiO₂) was prepared using gamma irradiation at different doses. Carboxymethyl cellulose was used as a matrix and TiO₂ in different contents was added (0.25, 0.5, 1, 1.5 wt%) as a filler. The polymer composite films were irradiated at doses of 5, 10 and 15 kGy using ⁶⁰Co γ-ray to form crosslinked network structure. The prepared composite films were described by different diagnostic procedures including X-ray diffractometer, scanning electron microscope (SEM), FTIR as well as thermal and mechanical properties measurements. CMC/TiO₂ composite films were used for removal of basic Violet 7 dye. The adsorption of the dye match with the Langmuir model across chemical monolayer adsorption performance. Adsorption kinetic of dyes was set up to be regular to pseudo second order kinetic model. The results showed that the prepared composite films significantly removed this basic violet 7 dye with maximum absorption capacity (123.6 mg/g).

使用γ射线以不同剂量制备羧甲基纤维素（CMC）/二氧化钛（TiO ₂）。使用羧甲基纤维素作为基质，并添加不同含量的TiO ₂（0.25、0.5、1、1.5 wt％）作为填料。使用⁶⁰ Coγ射线以5、10和15kGy的剂量辐照聚合物复合膜，以形成交联的网络结构。通过不同的诊断程序（包括X射线衍射仪，扫描电子显微镜（SEM），FTIR以及热和机械性能测量）对制备的复合膜进行了描述。CMC /钛₂复合膜用于去除碱性紫7染料。在化学单层吸附性能上，染料的吸附与Langmuir模型匹配。染料的吸附动力学设置为规则的伪二级动力学模型。结果表明，所制备的复合膜显着去除了该碱性紫7染料，具有最大吸收容量（123.6mg / g）。
