Shamim; Huq, S. M. Imamul; Kawai, ShigenaoNitric acid-perchloric acid mixture is the renowned digesting reagent in the scientific world of plant nutrition. Beside this, some other inorganic acids can be used as the digester of plant samples. Therefore, this experiment was conducted to find out if there is any difference between the digesting capacity of nitric acid (HNO3) and nitric acid-perchloric acid mixture (HNO3-HClO4) or not. The hydroponic experiments were conducted with barley (Hordeum vulgare L. cv. Minorimugi) and rice (Oryza sativa L. cv. Akihikari) seedlings. At suitable stage, the plant samples were collected, washed with deionized water, separated into shoot and root, dried, grinded and then divided into two groups for shoot and root individually for two types of seedlings. One group was for only HNO3 acid and the other group was for HNO3-HClO4 acid mixture. Phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), zinc (Zn) and copper (Cu) were measured after digesting the samples. There was no significant difference between the digesting capacity of HNO3 acid and HNO3-HClO4 acid mixture. Potassium was measured by diluting the samples (200-600 times) containing lanthanum chloride (LaCl3) or without LaCl3. Lanthanum chloride did not have any significant effect on K measurement in this dilution system.Item Arsenic contamination in the food chain and its possible mitigation approaches(J. Asiatic Soc.
