“…Comparative standardization approach was used in the determination of interested element concentration [10][11] [12] . Quality control was performed by determining elemental concentration levels in the certified reference materials NIST-1633b (Coal Fly Ash) and IAEA-SL-1 compared to IAEA-Soil7 and compared the measured values of elements with the certified ones as shown in Table 2.…”

The work focused on the elemental and physicochemical analysis in the textile waste (Effluent and Sludge) where two effluent samples and one sludge sample were collected from Grameen Knit Dyeing Industry (GKDI). Every effluent sample is divided into liquid sample (L1 and L2) and residual sample (R1 and R2). Neutron Activation Analysis (NAA) method used for the elemental analysis. The study revealed that, in the sludge (S) the Sb concentration was found 50.2 mg/L which exceeded the standard. Here Co concentration exceeded the standard. Here the highest Cr and Cd value was found in the (S) which exceeded the standard level. The total alkalinity, hardness and free CO 2 level of discharged water was harmful for the environment.From this study it is revealed that the sludge contain high content of heavy metal and other harmful elements. Soda ash method can be applied to reduce the 'Cr' concentration.
