Embodiment 1
[0035] The composition and production process of the preparation for reducing mercury content in rice grains are as follows: add 1L of water to the reaction kettle, adjust the water temperature to 50-60°C, and add 20g / L, L-selenomethionine 25g / L, cystathionine 40g / L, mannitol chelated calcium 150g / L, potassium pyrophosphate 100g / L, ethoxylated polytrisiloxane 5g / L And polyaspartic acid 15g / L, after adding each component, react at constant temperature (50-60°C) for 30min; until polyaspartic acid as the last component is added, react at constant temperature at 50-60°C for 30min.
[0036] After all components are added, the reaction product is cooled, filtered (through a 2500-mesh filter), sterilized (heated at 121°C for 20 minutes), and filled to obtain the finished product.
[0037] The above-mentioned preparations were used to carry out the plot test. The contaminated soil test plot [volume, 1m (length) × 1m (width) × 0.4m (height)] was built with cement. The soil used was co...
Embodiment 2
[0044] The composition and production process of the preparation for reducing mercury content in rice grains are as follows: add 1L of water to the reaction kettle, adjust the water temperature to 50-60°C, and add 25g / L, L-selenomethionine 23g / L, cystathionine 50g / L, mannitol chelated calcium 200g / L, potassium pyrophosphate 150g / L, ethoxylated polytrisiloxane 7.5g / L L and polyaspartic acid 15g / L, after adding each component, react at constant temperature for 30min. After adding polyaspartic acid as the last component, react at a constant temperature of 50-60° C. for 30 minutes.
[0045] After all components are added, the reaction product is cooled, filtered (through a 2500-mesh filter), sterilized (heated at 121°C for 20 minutes), and filled to obtain the finished product.
[0046] The above-mentioned preparations were used to carry out the plot test. The contaminated soil test plot [volume, 1m (length) × 1m (width) × 0.4m (height)] was built with cement. The soil used was ...
Embodiment 3
[0053] The composition and production process of the preparation for reducing mercury content in rice grains are as follows: add 1L of water to the reaction kettle, adjust the water temperature to 50-60°C, and add 22g / L, L-selenomethionine 25g / L, cystathionine 45g / L, mannitol chelated calcium 175g / L, potassium pyrophosphate 125g / L, ethoxylated polytrisiloxane 10g / L and polyaspartic acid 10g / L, each component was added and reacted at a constant temperature for 30 minutes; until the last component of polyaspartic acid was added, it was reacted at a constant temperature of 50-60°C for 30 minutes.
[0054] After all components are added, the reaction product is cooled, filtered (through a 2500-mesh filter), sterilized (heated at 121°C for 20 minutes), and filled to obtain the finished product.
[0055] The above-mentioned preparations were used to carry out the plot test. The contaminated soil test plot [volume, 1m (length) × 1m (width) × 0.4m (height)] was built with cement. The...
