Estimating dye concentrations in three-component wastewater by neuro-fuzzy technique

摘要

Several techniques have been suggested in the past to estimate the dye concentration in multiple-component solutions. This work explains new techniques based on adaptive neuro-fuzzy inference technique for measuring dye concentration in three-component wastewater solution. The performance of new method is compared with the normal Beer's law. The mean ternary relative error in Beer's law and neuro-fuzzy and PCA-neuro-fuzzy methods are 15.71, 6.044, and 5.814, respectively. The obtained results indicate that the performance of neuro-fuzzy technique is better than normal spectrophotometry method.
