“…Much research and technological work were done in this field to make the cellulosic fabrics acquire some additional properties such as flame retardant [1,4], antibacterial and UV protection [5][6][7][8], self-cleaning, [9][10][11][12] water /oil repellent, [13] crease and wrinkle [14][15][16] recovery. Also, to accept different classes of dyes [17][18][19][20][21][22][23][24] with remarkable improvement in dyeability and fastness properties. The most applied chemical modification techniques are graft copolymerization, [3,[25][26][27] finishing treatment with different types of finishing agents [28][29][30][31], UV/ozone [32,33], microwave [34][35][36] and plasma.…”

Application of reactive dyes with low fixation in textile coloring field has caused discharges of colored wastewater and waste of resources. In this work, to reduce the discharge and improve the utilization, three novel reactive dyes (D1, D2, D3) with high reactivity based on copper phthalocyanine‐azo skeleton were designed and synthesized, and the structures were characterized by UV–vis, FT‐IR, and 1H NMR. All these dyes had large molar extinction coefficients, and they presented violet, brown, and dark‐violet colors. The printing performances on cotton fabrics of the dyes were investigated. Results show that the printing properties of the dyes on fabrics were not obviously affected by alkaline concentration, urea concentration, and steaming time. In addition, the printing process leaded to colorless wastewater, and the fixations on cotton fabrics of D1, D2, and D3 were all close to 100%, illustrating high utilization of the novel dyes. The design and application of this kind of reactive dye could provide a significant approach for reducing the discharge of colored wastewater and saving energy.

Molecularly imprinted materials based on imprinting of dithizone‐Zn (II) complexes (DTZ‐Zn (II)) on the cotton fabric/silica, and Color Grab application for OPPO A54 were proposed and applied for the first time to detect Zn (II) ions in water samples. The proposed materials were prepared by using cotton fabrics as cellulosic materials, tetraethoxysilane (TEOS) as silica sources, and DTZ‐Zn (II) as template molecules. The initial concentration of DTZ and Zn (II), volume of TEOS and reaction time were optimized to obtain the maximum adsorption of the DTZ‐Zn (II) complexes in the imprinted materials. The concentrations of HCl and extraction time were optimized to obtain the maximum Zn (II) removal. The results were found that a 10 mL of a solution containing DTZ (0.20 mM) and Zn (II) (0.30 mM), a 25 μL of TEOS, and 10 min of reaction time exhibited the strong binding of template complexes. Zn (II) ions were selectively removed from the materials by using 0.1 M HCl for 10 min. The morphology of the prepared materials was characterized by SEM‐EDS and ATR‐FTIR spectroscopy. The smartphone based the cotton fabric/silica materials exhibited linear relationship between saturation (%) and Zn (II) concentrations in the range of 0.1 to 1.0 mg/L, with limit of detection (LOD) of 0.02 mg/L and limit of quantification (LOQ) of 0.06 mg/L. The proposed method was successfully applied to determine Zn (II) in real water samples with the % recovery ranging from 98‐115 and the acceptable relative standard deviation less than 6 (n =3).This article is protected by copyright.
