This study measured surface water temperature, water pH, TDS, EC, DO, nitrate, ammonium, sulphate and DIP as water physico-chemical properties of four freshwater reservoirs from Barishal Sadar upozilla. The surface water temperature was recorded highest (22.4 °C) in station 4 and loest was in station 1. Water pH, nitrate, ammonium and sulphate showed almost same results among the four reservoirs. TDS and EC values range from 188 to 215 mg/l and 195 to 225 µS/cm, respectively. DO level was almost similar in all the stations except station 1 which showed comparatively lowest amount (4.55 mg/l). DIP ranges from 3.20 to 4.15 mg/l. Among the four reservoirs, comparatively newly established BU pond (station 4) showed poor results than the others.

In the present study, carboxymethyl starch (CMC) were produced from different sources of starch and their physico-chemical properties were evaluated. Carboxymethylation was performed using different concentrations of sodium monochloroacetate (1.1, 1.3 and 1.5 mol/mol of anhydrous glucose units) in a three-necked round-bottom flask (250 mL) for approximately 3 h (250 rpm and 40°C) in a two-stage reaction comprising alkalization and etherification. The introduction of carboxymethyl groups was confirmed in the results by the appearance of a new peak in the FTIR spectrum in 1650.10-1649.76 cm-1 region. In addition, degree of substitution (DS) of produced CMS was ranged from 0.53-0.60. An increase in the concentration of sodium monochloroacetate (1.1, 1.3 and 1.5 mol/mol of anhydrous glucose unit) resulted in greater paste clarity, higher solubility and greater swelling than native starch. Furthermore, cassava starch (tapioca) produced a CMS exhibited greater swelling than sago starch, however by contrast, CMS-sago was more soluble and clearer than CMS-cassava.
