| Abstract: | The paper focuseed on determination of total cyanide in soil by pre-distillation-isonicotinic acid-barbituric acid spectrophotometry. The pre-distillation process made use sulfuric acid instead of phosphoric acid which makes the pre-processing better. Used a more appropriate method of isonicotinic acid-barbituric acid spectrophotometry. |
