AB  - In the present study, preparation of CuBTC-monopol monoliths for use within the 
      microchip solid phase extraction was undertaken through a 20-min UV lamp-assisted 
      polymerization for 2,2-dimethoxy-2-phenyl acetophenone (DMPA), butyl methacrylate 
      (BMA), and ethylene dimethacrylate (EDMA) alongside inclusion of the porogenic 
      solvent system (1-propanol and methanol (1 : 1)). The resultant coating underwent 
      coating using CuBTC nanocrystals in ethanolic solution of ethanolic solution of 
      1,3,5-benzenetricarboxylic acid (H(3)BTC, 10 mM) and 10 mM copper(II) acetate 
      Cu(CH(3)COO)(2). This paper reports enhanced extraction, characterization, and 
      synthesis studies for porous CuBTC metal organic frameworks that are marked by 
      different methods including SEM/EDAX analysis, atomic force microscopy (AFM), and 
      Fourier-transform infrared spectroscopy (FT-IR). The evaluation of the 
      microchip's performance was undertaken as sorbent through retrieval of six toxic 
      dyes (anionic and cationic dyes). Various parameters (desorption and extraction 
      step flow rates, volume of desorption solvent, volume of sample, and type of 
      desorption solvent) were examined to optimize dye extraction using fabricated 
      microchips. The result indicated that CuBTC-monopol monoliths were permeable with 
      the ability of removing impurities and attained high toxic dye extraction 
      recovery (83.4-99.9%). The assessment of reproducibility for chip-to-chip was 
      undertaken by computing the relative standard deviations (RSDs) of the six dyes 
      in extraction. The interbatch and intrabatch RSDs ranged between 3.8 and 6.9% and 
      2.3 and 4.8%. Such features showed that fabricated CuBTC-monopol monolithic disk 
      polycarbonate microchips have the potential of extracting toxic dyes that could 
      be utilized for treating wastewater.
