AC (particle size: 4–6
mm) and biochar were obtained from Henan province, China. Zeolite
(particle size: 2–4 mm) was obtained from Hebei province. Coal
ash (Shanxi province, China) and clay (Beijing local soil) were washed
with deionized water, dried at 100 °C for 24 h, and then sieved
through 180 mesh before use (particle size < 90 μm). Na₂SO₃ and diatomite were purchased from Beijing Chemical
Works (Beijing, China). Pure oxygen (99.99%) was used in this experiment.
All chemicals were analytical grade and used without further purification.
Water was obtained from a Milli-Q system (Millipore Corp., Boston,
MA).

Moso Bamboo Densification and TiO2 Synthesis

Check if the same lab product or an alternative is used in the 5 most similar protocols

Moso bamboos were purchased from the Hunan province of China and were processed into cuboid specimens with two sets of sizes, 80 × 18 × 6 mm for natural bamboo, and 80 × 18 × 1.5 mm for densified bamboo. Specimens were cut at ~1.5 m from the bottom of 5-year-old mature bamboo. NaOH (AR, Beijing chemical reagent company) and Na₂SO₃ (AR, Beijing chemical reagent company) were used in the delignification process to remove lignin and hemicellulose. C₂H₆O (AR, Beijing Chemical Reagent Company) and tetrabutyl titanate (≥99.0%, Aladdin) were used to synthesize the TiO₂.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
