Benefits of technology

This new type of material can be used for treating heavy metals effectively without causing harm or contamination from other chemical agents that were previously added during its preparation process. It also helps reduce costs compared to current ways such as ion exchange resin columns.

Problems solved by technology

This patented describes how certain compounds called aminosquicyclene (AQ) are found in plants that have many useful properties such as antimicrobial activity or antiinflammatory effects. However, they also bind strongly to other materials like copper cations used during electroplation processes making them difficult to separate from these substances without causing damage. Therefore there needs to develop ways to modify this type of material while maintain its beneficial functions.

Embodiment 1

[0022] Present embodiment formula and method are as follows:

[0023] 1. Take 100 parts of tapioca starch and disperse in water, then add 20 parts of sodium periodate, mix well, and react for 2 hours under dark conditions to fully oxidize the starch. Then, the product was washed 3 times with deionized water and 1 time with ethanol.

[0024] 2. Disperse the above product in an appropriate amount of water, add 30 parts of 8-aminoquinoline, adjust the pH of the system to 5 with acid, and react for 3 hours at a temperature of 60-65°C to obtain a crude product.

[0025] 3. After the reaction, take it out and cool it to room temperature, and grind it through a 100-mesh sieve.

[0026] 4. Wash 2 to 3 times with 70% ethanol solution, then put the product into an oven at 45°C to dry, pulverize, and set aside.

Embodiment 2

[0028] Present embodiment formula and method are as follows:

[0029] 1. Take 100 parts of tapioca starch and disperse in water, then add 20 parts of sodium periodate, mix well, and react for 3 hours under dark conditions to fully oxidize the starch. Then, the product was washed 3 times with deionized water and 1 time with ethanol.

[0030] 2. Disperse the above product in an appropriate amount of water, add 55 parts of 8-aminoquinoline, adjust the pH of the system to 5 with acid, and react for 4 hours at a temperature of 60-65°C to obtain a crude product.

[0031] 3. After the reaction, take it out and cool it to room temperature, and grind it through a 100-mesh sieve.

[0032] 4. Wash 2 to 3 times with 70% ethanol solution, then put the product into an oven at 45°C to dry, pulverize, and set aside.

Embodiment 3

[0034] Present embodiment formula and method are as follows:

[0035] 1. Take 100 parts of tapioca starch and disperse in water, then add 50 parts of sodium periodate, mix well, and react for 2 hours under dark conditions to fully oxidize the starch. Then, the product was washed 3 times with deionized water and 1 time with ethanol.

[0036] 2. Disperse the above product in an appropriate amount of water, add 55 parts of 8-aminoquinoline, adjust the pH of the system to 5 with acid, and react for 55 hours at a temperature of 60-65°C to obtain a crude product.

[0037] 3. After the reaction, take it out and cool it to room temperature, and grind it through a 100-mesh sieve.

[0038] 4. Wash 2 to 3 times with 70% ethanol solution, then put the product into an oven at 45°C to dry, pulverize, and set aside.
