Color Adsorption Performance of Bone Biocomponent for Textile Dyeing Effluent Treatment in Ethiopia

The continued expansion of industrial growth has contributed significantly to the economic development many countries. However, untreated discharge from textile factory significant impacts freshwater and public health. aim this study is explore economical-local wastewater treatment for local industries. experiment used waste bones as a source calcium-phosphate nanopowder (CNP) biocomponent, adsorbent azo dye effluent treatment. An isolated biocomponent was analyzed using FTIR UV-VIS, its adsorption isotherm also calculated. analysis CNP showed carbonates, amide, high-intensity phosphate peaks 1008 cm−1 1337 cm−1. effect contact time by UV-VIS absorption spectra revealed that 70% color removal achieved within 30 minutes 60 disperse red 1 (DR1D) DCT reactive blue 109 dyes (RB109D), respectively. In addition, effects condition parameters on percentage were DOE response surface methodology. maximum performances are 98.65% 96%, respectively, DR1D RB109D at neutral pH. Langmuir observed in with an R2 value 0.994 Freundlich 0.993. Finally, gauge effectiveness COD, BOD, TSS values before after deduction percentages 82, 87, RB109D; 89, 90, 89% DR1D; 71% industry sample, Generally, current good substitute synthetic adsorbents.
