Alkalinity sustained-release material for promoting carbon sequestration and sink increase in marine artificial reef and preparation method of alkalinity sustained-release material
The invention discloses an alkalinity slow-release material for promoting carbon sequestration and sink increase in a marine artificial reef and a preparation method thereof. The alkalinity slow-release material comprises magnesium hydroxide, sodium carbonate, glutaraldehyde, cement, a trimethylaminomethane buffer solution and water. Mixing sodium carbonate, magnesium hydroxide and glutaraldehyde with cement, adding water and a trimethylamino methane buffer solution, stirring, and shaping and solidifying in a mold after fully stirring, so as to obtain the alkalinity slow-release material. Magnesium hydroxide and sodium carbonate of the slow-release material react with free acid radical ions in the water body to generate absorbable soluble salt and salt for inhibiting the growth of algae. The slow-release material can increase the CO2 absorption capacity of a water body, has no adverse effect on the environment, can be used for manufacturing an artificial reef body, and can adjust the seawater alkalinity and promote the growth of corals besides the transplanting and fixing functions of the artificial reef body. By applying the slow-release material, the alkalinity of seawater is kept within a certain range, CO2 and seawater acidification are reduced, coral reef community recovery is facilitated, and seawater carbon sequestration and convergence increase are promoted.
本发明公开了一种海洋人工礁体中促进固碳增汇的碱度缓释材料及制备方法。碱度缓释材料包括氢氧化镁、碳酸钠、戊二醛、水泥、三轻甲基氨基甲烷缓冲液与水。将碳酸钠、氢氧化镁和戊二醛与水泥混合后加水、三轻甲基氨基甲烷缓冲液搅拌，搅拌充分后在模具中定型凝固，得到碱度缓释材料。缓释材料的氢氧化镁、碳酸钠与水体中游离的酸根离子反应，生成可被吸收的可溶性盐及抑制藻类生长的盐。该缓释材料增加水体CO2吸收能力，对环境无不良影响，还可用于制作人工礁体，使人工礁体除移植固定的功能外，同时调节海水碱度，促进珊瑚生长。通过应用该缓释材料，使海水保持一定范围的碱度，减少CO2和海水酸化，有助于珊瑚礁群落恢复，并促进海水固碳增汇。
