This utility model relates to the field of duckweed containment technology in waterways, and discloses a containment rope float suitable for fish spawning. It includes a containment rope made of first bundled reed stalks, with several reed balls made of second bundled reed stalks evenly distributed on the containment rope; each reed ball is filled with palm leaves; both ends of the containment rope are secured with ropes, and the other end of each rope is secured with a ground stake inserted into the riverbank. The advantages of this utility model compared to existing technologies are: it can contain duckweed on the water surface; the containment device decomposes quickly after disposal, does not pollute the environment, and provides a breeding environment for fish.

This disclosure relates to the field of carbon black technology, specifically a method for reducing the ash content of palm shell plant carbon black. The palm shell plant carbon black uses palm shells as raw material. The method includes the following steps: providing palm shells as raw material, carbonizing the palm shells to obtain palm shell plant carbon black; adding the palm shell plant carbon black to a first acidic solution and performing ultrasonic cleaning; then soaking it in a second acidic solution, followed by dry ball milling, and then soaking it in a third acidic solution; followed by wet ball milling; finally, after post-treatment, obtaining palm shell plant carbon black with reduced ash content. The method provided in this disclosure significantly reduces the ash content and other impurities in palm shell plant carbon black prepared from palm shells.
