| 1 | Question from Assoc. Prof. Ts. Dr. Ch'ng Huck Ywih | The research studied the effect of photocatalytic nanocomposite in degrading glyphosate which provides a green approach to remove glyphosate contamination in the soil and environment. The questions are as follows: 1) When should you apply the photocatalytic nanocomposite? Is it prior to glyphosate spraying or after glyphosate spraying? 2) What will happen to the photocatalytic nanocomposite after being applied? Does it have the natural biodegradation properties? 3) If the glyphosate is found in the aquatic environment, is it possible to utilize photocatalytic nanocomposite in aquatic environment? | Answer from presenter | 1) When should you apply the photocatalytic nanocomposite? Is it prior to glyphosate spraying or after glyphosate spraying? 2) What will happen to the photocatalytic nanocomposite after being applied? Does it have the natural biodegradation properties? Thank you for your questions. For your information this is a synthetic study which mimic on glyphosate in the wastewater pollution. If glyphosate is detected in wastewater, or sometime glyphosate compounds is not removed in WWTP effluent properly which eventually released to receiving water bodies back such as rivers, and as a result, contributed to contamination. Hence, this method can be applied to treat this issue. The spent photocatalyst can be recovered back by filtration system and of course this method should be applied with other method as well. This photocatalyst is not biodegradable. 2) If the glyphosate is found in the aquatic environment, is it possible to utilize photocatalytic nanocomposite in aquatic environment? : Possible |
